Hi, thanks for the log. Issue is known and caused by old incompatible transport station assets.
Wait for game fix or asset update. You can try unsubscribing old public transport stations but that might cause another set of errors.

Simulation error: Object reference not set to an instance of an object
at TransportStationAI.IsIntercity () <0x0019f>

@zaratropia if you see different variant of Simulation error: Object reference not set to an instance of an object please create another issue and attach log file. If you see exact same error there is no other option than wait for patch/asset update.

This error is not caused by TM:PE. We can't do anything to help you.

@aubergine10 could you update our troubleshooting section in wiki if you haven't done that yet?
I've seen confirmation it is a little bug in SH update which triggers not 100% compatible assets to throw an error.

Thank you for letting me know.
Appreciate it.

[aubergine10]

I'll update troubleshooting wiki. 👍
