I have my game set to update when one is detected
Today it updated and now none of my trains work, they worked yesterday but now something changed the signaling and none of my trains will go to any of my stations.
This is rather frustrating as I am playing on Railworld with a massive base that depends on the trains for all incoming resources.
at first i tried removing some of the chain signals that were poping up blue that didn't work to correct the issue.
I tried removing signals that even though they were showing green on the other side of the chain signals and that didn't work either.
None of the paths are showing any red except where there is a train already at the destination of another train and the red is only showing in the last segment of the signal chain.
Whatever the 'fix' to the pathing of the trains was please unfix it as it is broken now.

Since this doesn't seem to be a common problem, and might be almost impossible to reproduce in another save, the devs will almost certainly want a copy of your save.

I exited without saving and reloaded from the same save and all but one train works now its a fluid train I think the wait conditions need to be adjusted to get it to work right. It was a rather shocking circumstance when it happened as I'm on a railworld map and I have 35 trains running to keep my bus fed. I need to keep my head when things like that happen after an update instead of panicking.
