Error when creating new Train outside connection

[willbattel]

I've confirmed that the mod works for road connections but I am unable to create connections with train tracks. It does place the track but doesn't create the outside connection.

Argument cannot be null.
Parameter name: source [System.ArgumentNullException]

Details:
No details

Cities Skylines version: 1.10.1-f3 All DLCs enabled

No other mods are enabled except for 81 Tiles (Fixed for C:S 1.2+) - Allows to use all 81 map tiles by BloodyPenguin.

It used to work for me, but now I am having problems with it after adding 81 tiles (problem persists after removing 81 tiles)

I used the Extended Error Reporting mod to gather this stacktrace:
