Issue description:

Using a small modpack, 46 mods, the game crashes when entering a LAN game. the host keeps ok but the "guest" crashes as soon as the world loads.
looking at the crash report, seems like flamethrower is being checked and so is player state related to it

Steps to reproduce:

it may be mod conflict
1.Create a world
2.Host to LAN
3.Ask for someone to enter it

Version (make sure you are on the latest version before reporting):

M 1.16.4 F 35.1.37 .
Mekanism: 10.0.18.445

Please use search functionality before posting issues.

If you search there are like 8 issues that reports the same problem, please use, as said, the research functionality first.
Anyway it should be programmed to be fixed in the next Mekanism update iirc

Thank you and sorry for the inconvenience
