Hidden Depths: Ancient Guardian got stuck, could not finish mission
I was playing co-op on an underwater mission. the game was going fine until we reached the boss. We got its health down by about 15 percent. it then moved towards the furthest right out of player reach. It was still able to attack us with its guardian beam and summon guardians. the guardians also stayed behind the walls. They couldn't hurt us tho. We tried to get as far away as possible, we purposely killed ourselves, but it wouldn't move. we had to return to camp. Please fix this, thank you for taking the time to read this.

Same thing happened to me, both the ancient guardian and the elder guardian managed to get outside the arena. (Windows 10)
It also happens to me once
it was also annoying because I had to do the mission all over again
Both times we played this level with 3 players we had this glitch happen when the ancient guardian hit 25% life or less. No amount of running around or attempts to bait it out worked. We used the spinblade artifact with multiple players to finally defeat the elder guardian and the ancient guardian, but it took a long time. Arrows at the bridge area would get stuck in mid air and no kind of other projectile are effective.
What about fireworks? Try those next time!
