The pack is VINI_DAMIANI's but I have modified them. It's a custom pack which I put many other packs together and modified them heavily and... I set M200I's accuracy as 0 but it still buggy.
Anyway, I have been used ordinary Flans Mod before and it didn't have bugs like I said in this topic
I'm so glad to see you replied my topic
Anyway, I found another bugs... When I update FM+ to 1.0.4 , some models from Modern Warfare Content Pack and WW2 Content Pack were glitch and some of their model even didn't show.
And... some vehicles (From any packs) make the game crash when it was destroyed (Also make server crash when it was destroyed in multiplayer).
