Do you only have vehicle mod installed? Test he alone and try reproduce this problem again.

I also advise giving a more detailed description of the problem, to help the developer figure out the problem (if it occurs with the mod).

Some things like:

• Mod Version
• Forge Version (that you are using)
• Minecraft Version
• Log.txt (if it crashes and there is one)

It will help a lot!

"vehicle got stuck in hands" You picked up the vehicle. It's a feature in the Vehicle Mod. Crouch and right click the ground to place it back down. In terms of it crashing, I will look into the issue.

Closing because no crash log is provided. Open a new issue if you have the crash log
