Ok this is the second time i got hard summon bugged. But i got a theory that might help now with my experience... So the last time and this one i tried to enter the Hard Monster just few seconds after another guy entered... my theory is that whenever someone else enter the Hard Summon no one else can enter until the 15 min ends...
please GMs checks those notes i have provided.

P.s: i have just ended a Hard summon before that one that bugged...

Char name: AliceLight

thanks for the support.
