Official Answer is that they have not solved the bug from the previous dungeon, so they will skip it until they can solve it (the 0 points if you skipped capture bug)
And what's that stupid ball of energy beside my BPs on the Boss page?
When they added skills we had 3 Dungeons in a row, because of Raid bugs. This doesn't matter to me though, as I only farm anyways.
I'm fine with it, I like raid the most. Plus I get more souls during raid than tower and I need to level up my 4 Easter Princesses :D :D
