Describe the Bug

My Minecraft server has encountered this issue.
A player loaded a dynamic contraptions when entering the server, causing the server to crash.
I arrived at that location without causing the same problem (I have been here before), but when I entered the nether and returned, the server crashed.

May because the type conversion?

like i said. check whether your issue can be reproduced on pure forge. if not, then that is an issue that you should report to mohist.

mohist is not fully forge compatible, Please check if your issue can be reproduced in pure forge.
