Gates Of The Abyss can't count

[:1]Im on my first replay on frozen throne human campaign, and i think i have revealed a bug: in "Gates of the Abyss"

the game believes i shall deactivate a portal i have allready extinctioned, all 4 are allready closed i guess it didnt like that i did my own order on the 4? or the fact that destroyed the lilac orc base and every critter on the map before this?

i guess the only solution would be to restar scenario?, or insert the cheat that jumps forward one level (but keeping my heroes level and items i hope)

refresh my memory what this cheat is if there is no other solution?

patched yes
