Fort of the Damned Boss Glitch

So I was on a galleon crew with my friends. We were doing fort of the damned and the boss glitched into the floor of the island. 2 of us tried to sword the boss out of the spot while the other 2 went to get gunpowder kegs. The other 2 came back and we killed him and the key is still stuck underground. This needs to be addressed immediately so that people don’t have the same problem as us. For pictures of the issue I have put on my Twitter. @MHESSON1020. Devs if you see this please address the glitch
