Enemy Levels are limited to 9999 now, as during..... either the Breeding Grounds or Mutalist Incursions Events (i can't remember which right now), Enemies exceeding Lv9999 broke the game, w/ Enemy Spawns ceasing to function correctly. some things like Covert Lethality were also found to cease functioning over 9999 as well.

so for a multitude of reasons, the Enemy Level was limited to 9999. however, Eximus for example Spawn at current Mission Level + ~10-15. so those can still exceed the limit and become partially broken.
