Basicly timer stoped at 3:50 and tequatl disappeared although the event did not end and we could still deal dmg. After some time megalaser event activated – here teqatl appeard took laser with him and jumped into water ( we completed megalaser event sucessfully ).
Teqatl was still vulnerable to dmg and we still could deal dmg to the place where he stands. After some time we just completed the event and we got chest. I cant provide additional info bc i joined after he bugged.
I made some screens to help u understand what happend. Look at time and hp bar.
