Bombardon seems to have the animation and visual effect for its repeating attack messed up, instead of actually firing its gun, it looks like it's repeatedly casting a damaging debuff.

Also certain explosive weapons like the Ramjet or Gunship rockets sometimes leave behind a lingering weird burning sound in the background that sometimes mutes other sound effects, and I feel like this may have led my game to crash during one battle in a Vanguard city, although I don't know if that was actually the fault of the explosive weapons, or if its because of all the destroyed vehicles and their burning wreckages that cause lag similar to what Hero mentioned.

Will take a look...

Mod has a warning on the start of the game.

The endless explosion sound is still not fixed =(
