Hey
I found a bug.
The bug crashes the game when triggered. I will now tell what i did.
I started my minecraft with this mod and some content packs(the UNU Civil pack and their must have packs) and loaded in to a minecraft world. I took UNU poles and placed them. now i took a vehicle and placed it on the pole and then minecraft crashed.

Here´s the latest log from my minecraft:
latest.log

There's nothing in there that indicates a crash. Could you post the crash report?

Here is the Crashreport

Rodger that. I know exactly where this is. Will fix.

Fixed in V19.15.0 due to the new pole interaction system removing this potential failure point.
