abyss not closing in corrupted map

t1 map, abyss doesn't close, 0 monsters remain. corrupted, as in the atlas thing, waystone not corrupted. no other modifiers. map still shows green abyss dots on section of abyss. some of the monsters in the area where it's still green were 'revived' as different monsters that i have never seen before that i assume is related to corruption, and was happening here and there all over the map.
