mobs spawning outside of the playable map

i have never been this frustrated before, please fix this. if nothing give us a "teleport to mob" button until you fix it or something, i just spent 30 mins in a map, clearing it just to realize its impossible to complete because of this bug. i had the whole map explored. 100% explored, all mobs on the map dead, everything done. but last 2 rares and 31 mobs were on a different part of the map completely that was more than 1 screen away from closest spot you could get to it.

i get this is early access, i just hope this gets fixed faster, i saw a thread from january about this, so its known for a long time now.
