I have modified a TEC light frigate, mostly by changing its stats in the appropriate entity file, while keeping strings and angular velocity intact, added an extra weapon to the standard design and a few muzzle Points in the corresponding mesh file. It all works until about a few minutes into the game, when it just crashes with a minidump message. I couldn't  identify any element that could trigger that error. Sometimes it occurs right after the ship's explosion, before it enters Phase or while the ship is firing (although the muzzle points seem to be working correctly).

Additionally, I'd like to ask whether the actual minidump is of any use. Does it contain any error messages, object variables, or just about anything that could be used to determine where an error might have occured?
