I'm glad you asked. I already considered both of the cases you mentioned. Bouncers would be allowed if there are only found gun crates/barrels. And I made special code so that objects created by (simple) MCEs would always be properly detected. And weapons from events other than the generator event are properly detected as well. The only case I didn't cover is when ammo or powerups are placed within a crate as an extra event since I figured no one does this regularly. I'll probably add support for it in the next update though.
