Specter doesn't get close enough to the player.. which makes his projectiles despawn before they can hit. 

thanks for the report! we are going to look into it 

Also Emilio, think you could take a look at the rift monster thing? It spawn about 1-2 enemies each second.. was 20-30 enemies remaining when I found it. https://imgur.com/YwjHArw (About a min later)
Edit: Found out by reading other thread that this is intended when there are to many files.

Got 2 different Fatal Errors in Knight boss room when killing him.

+ Camera in that room is very zoomed out, could barely see what was going on ingame before getting close to boss. Was safe from him though, since he spawned in the floor. 

Might also want to look into Magic Wall.. as it block enemy projectiles, deals damage to enemies and you can place 50 of them anywhere on your screen before running out of mana. https://imgur.com/NkLLPpX
Edit: Will also add that this made it possible to kill knight boss without moving because of the zoomed out room. Lantern boss got easier as well, since you could leave the walls on his lanterns.. killing them instantly as they came back to life. 
Edit 2: It gets a bit crazy when you combine it with potion use and equipment boosting stats.. https://imgur.com/fciiZLu
