[Crash] Minecart-Contraption assembly fails on 1.20.1-1.2h (Fabric)

[joernott]

We're currently updating our modpack to 1.20.1 and added Create Diesel Generators 1.2h in alpha3. One of our testers tried to assemble a minecart contraption in alpha3 and it crashed the game. Loading the saved game fails as it crashes every time. Loading the same saved game in alpha1 (without the diesel generators) works.

Minecraft version: 1.20.1 Create version: create-fabric-0.5.1-f-build.1335+mc1.20.1.jar Create Diesel generators version: creatediselgenerators-1.2.2h.jar

I've attached the full log to see the full java stack trace, module list etc: 2024-04-02_minecraft-log-gambal.zip

The fabric version isn't finished and is very buggy. for now you can: a) downgrade b) wait for the finished version

[joernott]

Solution b it is then. Thanks for the quick feedback and your great work. It is really fun to have all those mods in the Create environment.

I just tested 1.23h and it looks like assembling a minecart contraption works now.
