Yes, there are some rounding errors that require you to keep this loop topped up from time to time. It's not much, but it's enough to dry out the loop if you have no mechanism to top it up. I've seen some discussions on it and it's not something that can be fixed.

One thing I am worried about with the quality of items is how they behave in GUIs and item stacks. If I put a quality 5 (supreme?) cog in the assembler and want to add another cog of other quality 1 (subpar?) — are the qualities summed/averaged/combined somehow or is the slot "locked" and...

That should be in the py codex. There is a button to switch between researched, not-researched, and even selected and unselected TURD.

With the addition of both queue's, have deadlocks been resolved? I saw no mention of this in the FF, and it was the first thing that crossed my mind as an interesting topic to discus. Imagine a task to cut down a tree, and another to build a building in that location. What if both tasks are assigned...

Nope sorry. I did try to retrace my steps but nothing i did after caused a new crash. I've put everything i could find in my post above.

I was working on some circuits (very simple, 10x stacked stone = stone) and hit a button that showed tons of info on zinc plates (py mod). Game asked me to share factorio-current.log, so here we are. Edit: Attachments failed Edit2: The screen i popped up must have been ctrl+shift+f on a zinc plate. ...

Probably, I've read that the first tier reactor is only used for side products you need on some tech.

Note: I'm not at this stage in the game, but i used some tools to analyse the situation (you got my curiosity) There is the chain turning it into Unslimed Iron after which it will go through Stages 2 to 7. Or the chain turning it into Iron Concentrate, Fine Iron Concentrate, which can also be turned...

Have you tried to burn the resulting tiles? Burning should allow you to get rid of them.

But i'm not loading onto a faster belt. This is 2 yellow belts feeding into each other.

Somehow my belts started to side-load onto a full lane?!?

It happened in my modded save, so i'll just have to share that one. Also added a few recordings with different debug modes on.

I started the game with no sound device. I then got the message "Couldn't initiate sound, audio is disabled" I then enabled my sound device (enabled it on my kvm switch, but i guess this is the same as plugging it in) I wend to settings->sound I switched output to my now added sound device...
