Minecraft v1.20.1
Forge v47.1.47
Automobility v0.4.2

When breaking a slope in survival with no tools, I got this crash.
Crash Report

would love a fix for this, cars move too fast and glitch out on stairs and slabs and we are trying to build a highway for our survival server. slopes are much needed for this mod to traverse up and down

Same issue here, please fix

Same issue here, please fix

How to use fix? I haven't been exposed to building before

I've got what looks to be the same crash. It will crash the client but not the server. It will happen when the breaking particles start regardless of what is used on it. The item on the ground, in inventory, and placed is fine. I did make a fresh install with just minecraft 1.20.1 and forge 47.2.1 and Automobility 0.4.2 and it still happened. I've got 3 people on my server that get the same error. Hope this info helps! Thanks!

There's nothing I can do, I don't know English. I use translation software. You can try digging for survival
