Did my first solo BM, went well zombies acted as expected, no issues. but....
-Zombie corpses now lootable thanks to Survagers Zombie Loot Modlet which can be found here.
II found that i wasnt able to loot the corpses before they despawn, unlike the yellow loot bags. This might be intended to keep the ground from being covered in zombies, which would be cool but performance wise not sure
Usually when that happens to be, the game loads part of the recipes, and stops after one that errors out....shrug
