Some random enemies from a random previous encounter fill up the enemy side but dont take up any spots for example.
Goblin | Wolf(Shows HP and portrait but there is no wolf there)
Goblin|Wolf(Shows HP and portrait but there is no wolf there)
Wolf(Shows HP and portrait but there is no wolf there) | Goblin Archer
They only take up empty spots and can't get targeted or damanged, nor do they attack. It's quite annoying and save and load doesn't fix it. Sometimes the enemies get replaced with new ones too.
