Crypt map is bugged

Crypt map (Endgame) has a lot of issues with spawning enemies from Strongboxes, Essences and issues with League mechanics.

- Strongboxes wont spawn enemies if there's not enough room making them impossible to loot.
- Enemies trapped in crystals don't drop essences.
- Expedition bombs can't be placed in some corridors, behaving as if there is no line of sight. (blocked by pillars maybe?)

Basically enemy spawn issues from events and bomb placement is iffy.

I'm experienceing the same issue with placing expedition explosives.
I think it sees sections with pillars as impassable walls.

I recently encountered a bug where the only monster left was 1 rare and it had no life bar, it was invincible. Thus I'm unable to complete the map. I tried logging out but when I came back its still invincible.
