To Reproduce
Steps to reproduce the behaviour:

1. Host a Forge FML server with the latest release
2. Spawn any vehicle with weapons on it
3. Load and attempt to fire (if you get that far)

Expected behaviour

A crash should be expected and a full server restart required to repair it

N/A
Versions (please complete the following information):

• Forge: 14.23.5.2837
• Flan's Mod: 1.12.2.5.6, the latest one found under the releases tab here on Github.

Additional context

The server owner is out of town and i dont have access to the machine that hosts, so im unable to provide a crashlog immediately, when able i'll setup a local server to get one from.

@Modsojoy do you have a crash log yet?
