.fbx I make out of Ark's originals seems to be corrupted (Error 0x00000040)

[anothercaveman]

Hello!

So I recently managed to start modding Ark.
I am currently trying to get used to the new mesh/material import, which is pretty easy until now.

I just got a little problem:

I exported OneShotRifle original mesh into a FBX, (FPV and TPV), replaced them both by my LeeEnfield mesh, renamed it correctly in the FBX etc.

But then, here, at this very precise point, when I export my file (so the file used to be WeapOneShotRifle but is now a LeeEnfield right), it will get corrupted.
I am exporting triangulated, FBX 2011.
By corrupted I mean: I cannot open it back with Max, software will crash and If I try to load the mesh in the game, it will simply give me the 0x00000040 error.

I guess the issue is in the exporting, or in the rigging, because I already displayed the mesh with no problem - the problem happens when I get it in my hands:

Trying to get my Lee Enfield model into the game:

Thanks for your time !
