Hi, this is my first crash, just dropping here, hope it's helpful.

I really have no clue what caused it. I was organizing my quickbar at the time and making some new deconstruction planners for train tracks + signals. That's about it. Edited to indicate that this happens while hovering rail signals, probably nothing to do with the quickbar. All vanilla, no mods or console commands.

I'm on a mid-2012 Macbook Pro, recently updated to Mojave, had one Safari page open in the background as well as Steam.

Reloading from the autosave, it seems to happen when I go to place a signal on the circular 4-way rail intersection that I load in next to. Just happened twice, once pretty immediately after loading the save, and again after waiting 5 minutes or so, not doing anything.

Do you have any reliable way to reproduce the crash? Just loading the save and placing some signals/removing them doesn't seem to cause any crashing for me.

Yes, seems I can reproduce it by loading, selecting a standard rail signal, and hovering over an open slot (not placing anything) on any of the inner lanes, leading out of the roundabout. Hovering the signal on other parts of the intersection doesn't seem to cause a crash, but any of these places does. I took screenshots from the last frame, crashing it 4 times this way.

Sometimes it takes a few seconds of doing this before it crashes, but this crashes it reliably for me.

Think I realized what it is: I had the train visualization length set to 10. Setting it to 4 and trying again, hovering / placing signals in those same spots, did not cause a crash.

Tested this on a separate save where I had built the same roundabout with no issues, and removing all signals and trying to place a signal there crashed it as well when the train visualization length was set to 10.

Thanks for the report. It's now fixed for the next release.
