Blight Bug

I have run Blight hundreds of times , when summoning portals gets close to objects (such as statues) in maps mobs that summon from that portal gets stuck inside the objects, therefore i cant finish my blight encounter

That problem doesnt happen all the time , but i encounter the problem more than 10 times

thanks in advance

I just encountered this bug for about the fourth time this league. The blight portal is right next to a completed Crimson Iron deposit, an enemy is stuck in the portal that can't be hit by any of my attacks or abilities, and the encounter can never finish. Bug report #3,974,397,644.
