Idk when and why it really happens but after we crafted steam locomotive and launch it on rails server is crashed. It happens several times. I think it happens after a coliision with player/mob but not sure.

Minecraft: 1.20.1
Forge: 47.1.0
Mod version: 1.7.2 from curseforge

Here is curseforge profile for our modpack: Minecraft Sakurasou.zip

Here is crash reports:

crash-2023-08-02_00.04.43-server.txt
crash-2023-08-02_00.15.18-server.txt
crash-2023-08-02_00.31.51-server.txt

Hi, I uploaded the new version to curseforge with the fix.

Hi, I try to reproduce the error. It caused maybe by an incompatibility between improvable skills and my mod. The fix will be released in this week, in the next patch (with other fixes and a new locomotive type).

Thank you, seems like it works

Ok, it's crashed again

Hi, I try to reproduce the bug, but I can not. So I try to fix it by the description:
https://github.com/Xannosz/BetterMinecarts/releases/tag/1.8.2
Please try it, maybe it solve the problem.

We played several hours and try to test locomotive behavior and has no crashes
