If you save the multiplayer map to your computer and load it in single player mode, what FPS and UPS do you get?

Do you have any train mods installed? Some do automatic refueling schedule stuff if you name the stop in a particular way. When you add the station to the schedule, is the schedule entry dark gray/black, or is it light gray/white? The lighter color indicates a temporary entey that will only be visit...

Thanks! Would the Space Exploration beacons also cause this bug? I've noticed the copy-paste issue with that mod too. SE has a set of rules where some recipes work on some surfaces but not others, and some buildings/ghosts get swapped by scripts. You'll definitely need to investigate it separately.

Yes, there's no reason to use a chain signal before a station on a one-way track. There might sometimes be a reason to use chains on the single rail connecting the two groups of stations. Does the problem still happen if there is a chain signal exiting the buffer stations?

Can you share the timestamp when the "no path" text appears over the train? It's hard to see in the video. It does seem like the trains behave normally overall.

One thing to keep track of when testing is if any of the recipes are locked behind technologies. I know that can cause blueprints to be funny sometimes, and if a mod does something unusual like re-lock a recipe even weirder things could happen.

If you're asking if a 1-year-old CPU will perform better than a 13-year-old CPU, I don't think anyone will hesitate to say yes. It's more than three times faster just in clocks. The change from DDR3 to DDR4 will also have a big impact. But still, it is possible to make a big enough factory to lag a ...

LOL :D Okay, I knew that the base isn't small. But what are ways to bring it up to 30 PFS at least? Start a new game? :) That's an impressive map... First loading, I got 7 UPS. After I killed all the biters with the command line (there were 45000 enemy units mostly trying to pathfind to your base a...

There is no problem, you just need regular splitters. If you provide enough to begin with, the machines will consume what they need and the rest will back up on the belt, forcing the unneeded items to take a different path towards another machine that needs them. Oh. I just realize I could set a in...

Remember that while the vanilla Factorio engine is heavily optimized to minimize cache misses, the Lua interpreter that runs mod code is not. Large, heavily modded maps might not see any improvement from Vcache at all, so physical RAM latency is still important.

I've noticed that a pipe as well as a tank displays only liquid level but not flow speed. If there's no flow speed how can a player know how it's working if the fluid level is irrelevant? The only entities which show flow speed are steam engines/turbines & (offshore) pumps I know of. Perhaps I'...

It's logical that you need an input of 60/s to be able to consume 60/s. We're talking about Steam Level. If that's up to the max, there isn't a problem to provide constant flow needed (or we'll see if it drains that there's something wrong). The fluid level in a flowing pipe is a stable equilibrium...

If I have a stock pile of green circuits, gears, iron plate, copper plate, etc. I can handcraft most products for early game. Belts is something I like to automate, too, because it is used en masse. I agree, even in late game I set my logistics requests to a stack of all the main intermediate produ...

This is a bug in the Global Variable Viewer mod because it naively walks the prototype tree which includes a doubly-linked 2-level tree of LuaGroup objects. The LuaGroup for the subgroup has a reference to the parent group, and the parent has a reference back to the subgroup. This should be handled ...

My first mod copied a few subroutines from another mod. I messaged them, asked for some advice and if they minded me using that code. Most folks are reasonable if you ask politely. You may have already figured it out, but there's lots of "mods of mods" that change the characteristics of an...

I was going to pile on the train of "don't use LTN for that", but then I tried it for myself. The "Merged Delivery" feature does in fact allow multiple items to be loaded into one train, if they are all requested by one station and provided by another. A minimal amount of circuit...

It's not the only way. You could have a second combinator that you turn on to make the price and request thresholds 1 billion each. Or pass the wire to the stop through a logic combinator that acts as a switch, and have another constant combinator that controls whether it passes signals or not. (Ari...

There is no way to assign a global name to a custom event ID. When cross-mod compatibility is needed, you will need to add a remote interface so that mod can ask your mod what event ID to register.

If you have any other signals wired to the LTN stops, like the buffer chests, that is all it takes to turn it into a provider (positive items) or requester (negative items). It uses defaults for everything else.
