last night around 11 p.m. central time i found a raid boss octopod lv 30 in volcano 9 normal. this morning i went to raid boss option to fight the boss but it wasn't there.

Happend to me as well I found one and 2 buddies of mine did, then this morning all 3 are gone. Me not my buddies can access them and our pal lists are gone. Please fix this happening so many times and I can't get essences
