If I can reproduce it again I'll grab a new save.

I've had this happen multiple times on complicated rail blueprints and in some cases I couldn't figure out which signal might be causing the problem, picking up and replacing all of the red signals didn't seem to do anything.

I've been having an ongoing issue with certain fluid wagons not getting connected to the pumps at some times. This seems to be happening after loading a save with a train stop heading north. I'm not 100% sure if it's only on loading that this happens but that is when I have noticed it. The train is ...

When attempting to stream Factorio from an OSX machine running Steam but which has no mouse currently attached I get an error about mouse initialization failing. Connecting a mouse temporarily fixes the issue.

Seems to be fixed in 0.15.6. Thanks devs!

When I had heat pipes going only east and not west, the heat made it all the way to all of the pipes. According to all of the posts I ...

I built a large Nuclear power plant with 32 reactors and am seeing something odd with the heat pipes. My current blueprint has 3.1k heat pipes laid out in a large grid (4 nuclear reactors square) with the reactors in two columns in the center. The heat pipes to the right side heat up to more than 80...

Doesn't happen with 0.14.23. If I launch the game then quit while the initial loading bar is on screen, I get a crash before the loading finishes. 0.000 2017-04-25 00:29:54; Factorio 0.15.1 (build 29050, mac, steam) 0.000 Operating system: Mac OS X 10.12.4 0.000 Program arguments: "/Users/paper...

I've been playing on some saves named after the version of Factorio I started the game on for tracking purposes (ex: "0.14.12 - 1") and they work fine on the machine I created them on but when I tried to load them on another computer they simply weren't there. Looking at the filesystem, th...
