Oasis map - mobs stuck outside of the map

Hello :)

So I did my first oasis map with a t5 waystone.

I cleared the whole map then, and the game showed me where the last rares were. The only problem is, they are outside of the reachable areas.
I added an image to showcase this predicament.



I wish you all a wonderful day and keep up the good work!
