Maps crashing while playing - I'm sure this is a repeat complaint

I was progressing through a tier 6 corrupted nexus map to progress through the endgame. The map was Seepage. The game crashes with my character in the map. Restarting the game and choosing character works, but entering the loading screen doesn't. The game loads till about the point where you would see your chracter in the game, then crashes. Happened multiple times on this particular map but has happened to me before on other maps. Has even happened prior to Dawn of the Hunt. Have to wait the fifteen minutes for the map to expire before I can get back into the game.

Not being able to play because of some bugged map or game condition is annoying but not too bad. Losing a potentially heavily modified map burns my resources, more annoying, but I can get more I guess. Losing a corrupted nexus feels extremely bad. The time it took me to path to that nexus is gone, along with the resources cost and inability to play the game.
