@Youri: The root cause is the same as the report that Loewchen linked. When picking up from the entrance or exit to an underground belt, the inserter can only grab the item from about half a tile worth of belt. That means anytime the items on the belt are moving quickly, the item will be out of rea...

I believe that's a related issue, but not the same. My belt is *fully saturated*, as it's being produced by a vanilla loader. I explained this in my original post. Looking at the devs' response they deem it not a bug, so I guess that's all for this one. I was honestly quite pumped to go with a belt ...

I was testing some belt designs for science production and came across an odd behavior. I've got an input belt running underneath my science assemblers via undergrounds, and inserters pickup items from the undergrounds. Today I've found that if these inserters pickup from the underground entrance (n...

I've been experimenting with my train system recently. Currently I'm looking at the potential pros and cons of *mixing LHD and RHD* together in a single train system. The original idea came from the fact that most intersections have very short/easy turns to one side, while turns to the other side bl...

It seems the round-about might be my issue. My 2:8:2 train is heading to a stop and half-way through a round-about that stop becomes inactive. I believe in pursuit of the next available stop the train paths through itself - destroying any of its own wagons on the way. I've never seen this happen so...

This is absolutely a problem I've encountered in 16.28. I've had multiple trains run into each other and be destroyed. I've never had trains running on automatic crash into each other. I don't dare play in 16.28 for fear of more trains getting destroyed. It would be interesting to see at what areas...

I was driving through my base in my train, at low speed, when right next to me two automatic trains collided in a rail crossing that should be collision-safe. https://i.imgur.com/XdQAOnX.png I was driving the black train at the bottom. Right after this happened I got out and took the picture. There ...

I just had another one of my trains becoming bugged in the exact same way. This happened on 0.16.28. I immediately checked my autosaves but unfortunately even the oldest one was already after the train got bugged, so no luck there again. I must have been pretty close to catching it though, as I'm se...

Looks like: https://forums.factorio.com/36975 Do you have a recent save before it got stuck? That indeed looks like it's about the same problem, that one didn't show up when searching threads. Unfortunately I've since continued playing so there is no chance that any of my autosaves are from before ...

Roboports only show lines to other roboports within a certain distance of them. I don't know if this would be considered a bug or not. They only show lines when their red logistics areas connect. In the center of both images you can see the two separate areas connect. Not all lines are shown howeve...

I've omitted any other information such as a savefile or logfile as these shouldn't be needed/relevant; the problem is clear from the above images and description. As you can see I already noted that there is absolutely no reason for such files for this specific problem. There are no weird oddities...

A long time ago we received a nice visual to show which roboports connect with each other via a thick yellow dashed line. Soon after an algorithm was added to not show all of the lines as it would otherwise block the player's view. But I just ran into a situation where there were too few lines. http...

Sorry, it's been attached now.

While I was out adding new mines, one of my trains has seemingly stopped working. As I was out adding new mines I am unsure what could have caused this issue, I may have added some tracks very far away, and I may have added a new train stop irrelevant to the train, but none of that should affect it....

With the recent DyTech updates, it's become rather easily possible to boost machine speeds to incredible speeds. However, my productivity on these machines seems to be quite literally unable to keep up. The crafting speed of these machines is currently well over 200, though 100+ seems to already be ...

Updated my game from 0.11.19 to 0.11.20 today, got a crash at the end of the update but the game did manage to automatically restart, in the proper new version. In other words, I got an error but it appears to me like nothing odd happened.

With such a division in opinion, and several alternatives brought up, I must say I was surprised when I didn't see the solution that I thought had potential. And while I'm at it, I'm going to give a quick run-down of the pros and cons for each of the proposed alternatives. Quick note; I've seen post...

Whilst playing my own save, I got an unexpected error and the game quit on me. The map I was playing was originally created in SP, I believe early 0.11, but it has also been opened up to MP before. Whilst encountering the error it was in SP mode. The crash occured as I was sandwiched inbetween a Rob...

I did, apparently not good enough. Just now I saw a mention of it on reddit

Tried to connect to my friend's map, but whatever we try my game crashes after receiving the entire map. I've played with a friend on a map that he was hosting. I think we last played together on 0.11.10. Most stuff worked fine, I was even connecting as a W7 user to his game running on W8.1. We had ...
