Oba's Cursed Trove Crash

Crashed in Oba's Cursed Trove

Map 1: Tried 3-4 times, lost all portals.
Tested a different path, was able to progress smoothly. Went back to original path/point of crash, seems like it only crashed when certain creeps where saw/killed on screen

Map 2: Tried to see if it would crash again, same thing happened.

[EDIT]
I crashed at Olmec's as well
