Not the bosses drop items, but the crystal. Tried to break it (hit or something)?

I am running android 5.01. Character name Ohuneu.
I have had this glitch and one other occur many times as well. The map just breaks. You kill the boss and then you are stuck. You can't break the crystal. The guardians sit in the reset position as shown in the screenshot above. No exit. No loot. Lost 1 energy. It is very frustrating.
Related scenario. If you go in to the map with one other party member outside and they disconnects (another bug that eludes patches) or even leaves the party, you will be unable to invite anyone else to join you. The 3 bosses are flagged as active or something and can't be reset. Only happens on the 3 guardians for me.
