i tried to do Raid in Unison with 4 of friend. my 1st. choice was Gnome raid for 6 people. it worked well. after that we tried Pillar Raid.. in the middle of Raid we were wondering why hp from pillar become full again and then appear information that the game have been paused.
i tried this raid for about 1 hours but we gave up because it make us tired because of uncertainty that we will success. hp from pillar always back to 100% and this "pause game " information always appear.

anybody can give me a clue , what is wrong with this raid?
or
i should avoid some movement?

answer from GM also would be great to hear.
