Q: How do I know that this is the case of this crash? If i reproduce it without mods.

Q2: I need to reproduce it in the mission editor?

I can ask my players to reproduce it without mods. But I'm not sure that they succeed. Need more time.
If i understand - that mods can't contain direct processor instructions (physical machine code), they performed some kind of "virtual machine." Or I am wrong?
If the problem is the mod error, let this machine correctly handles the error rather than crash. =)

I can't add gzip archive as attachment. Is it correct security policy in this site?
