Can't Access Items after Boss Kill (Dig Site Map)

The boss on Dig Site map crashes pillars on both sides of the map during the fight. If you had any items that dropped on those parts of the maps then you won't be able to reach them. I ran this map while it was overrun by abyss and I have abyss chests, mobs, and items on the sides of the map that I can't access now.

GGG, please remove the destroyed pillars on this map after the boss is dead or don't let abyss spawn in the boss area.
