Blight Bug Monsters Stuck In Statue Blight Does Not End

I started a blight minigame in a T15 City Square map. Everything was functioning normally until the last monster portal appeared, just as Cassia mentioned "It's branching Exile!". The portal appears to be inside of or extremely close to a statue in the area, so when the creatures spawn in, it looks like they are trapped inside the statue. This has made them invulnerable to all damage (that I can dish out). I exited and entered the area to see if that did anything, it didn't. Unfortunately, this results in the blight minigame to be locked as incomplete. However, the other portals did close and I was able to loot them.

I have two screenshots for reference.
