The game crashes if I try to use CGM ammo in helicopters.
Crashreport: https://pastebin.com/CMNxB5dG

I use v5.2.2 of Simple Planes and v1.3.7 of CGM, both for Forge 1.19.2.
I have the Forge version 43.3.0 if that may be important to solve that problem.

It would be nice if anyone could tell me if it's a real bug or a mistake on my side...

Its been a reported issue since January, seems to be 1.19.2 exclusive and completely ignored by the developers. The crash is not your fault.

edit: actually, the crash is reported as far back as Sept 2023, way before I expected
