All three other players desynced when the fourth one left.

I have, right after building the station. But it was a name that was not used by any other stations, and before I even built the trains that I later made stop there.

If you click a link in one of the Steam news posts about a new version, such as the latest one (0.13.9) it sends you to: (https//forums.factorio.com/28892) which Firefox in turn then turns into: http://www.(https.com//forums.factorio.com/28892) Might not be under your control, but it kind of defeats...

See the attached save. I found it like this, I don't know how this situation came to occur.

There is a similar thing with the range indicator for turrets, which is rendered over their own bases but under their own barrels.

Perhaps it is a good idea to just render these previews over everything, to avoid the "problem" altogether.

Although one could argue there is never a need to open transport belts or inserters and the like while holding a placeable item.

My apologies, I was not aware of this setting. It was indeed 0.20. Was it added recently? I recall setting everything to the maximum a while ago.

I also just noticed it happens with inserter bases, rails, and parts of the train station.

To make matters worse, with 0.13 the circuit network allows opening of entities such as transport belts and inserters. It is these entities' GUIs that keep popping up when I place concrete. I'm now not 100% sure anymore the concrete is actually placed. I thought it was but it doesn't seem to make se...

If you put concrete under the cursor, and click somewhere to place that concrete, and that somewhere happens to be under something that can open a GUI, the GUI will open. The concrete will be placed as well. Essentially the concrete placement click is not consumed, and caught by the entity. This can...

Turns out making Factorio GIFs isn't all that hard

See the screenshot. The concrete has not yet been placed, and the preview appears over the the bottom half of the turret. It also occurs with "blue" previews, if there is concrete there already.

Another one of these, I'm afraid. If you load the attached save I presume you will find this situation. It was like this when I arrived, I don't know what went on there before that. Presumably it killed the other turret and is now trying to kill this one, which ran out of ammo. Maybe it has to do wi...

If you load the attached save you should be on a belt. Zoom out a lot, and as you move sideways, you'll see artifacts in the lighting on the circuit network over time. If you move around yourself the effect is much faster and appears to flicker. Of course, this only happens at night.

I did some more testing, and it turns out than after a reboot the issue disappeared. So phew, but apologies for the bug report. It was the one thing I forgot to test. I hadn't expected it as I had just booted to begin with XD

Since 0.13.6 I've noticed that the application hangs for a fraction of a second once about every 3 seconds. I originally noticed it when I was walking around after loading a save, but it occurs everywhere, including in the menu, and even in Windows itself when I temporarily alt-tab out of Factorio. ...

I got the same issue, in 0.13.1, with Logistics this time, in 1680x1050.

I finally discovered what was causing this. If you grab a blank blueprint out of your toolbelt, and then drag to create a non-blank blueprint, the toolbelt "forgets" that the blueprint was in it. Then when you order construction of your non-blank blueprint (without ever putting it back in ...

Did you try validating the game (Right click game -> Properties -> Local Files -> Verify Integrity of Game Cache)? It should replace any missing files.

I think even just reloading the save makes it go away.
