Opcodes warnings are mostly cause by game modifications, especially by the vehicle ones. Do you use any of these?

Edit: Sorry, posted with the guys above the same stuff...

Edit#2: After a quick reseach I discovered that this specific opcode warning is caused by vehicle components from the vehicle modifications workshops. You are most likely using vehicle modifications which interfere with these components and find them to be invalid, therefore your game eventually crashes. In my opinion, you should get rid of those components.
