Abyss in Digsite Boss Arena - Rewards unreachable

I ran a digsite map with a boss and an abyss. The abyss spawned in the arena (intentional?). I killed the abyss, spawning the rewards trove. I didn't loot mid-fight, so when the boss summoned the pillars, it blocks the rewards trove. The rewards are unreachable
