Meteor Shower bugged?
never mind.. I guess i was like 1 kill off getting it.. skill was full just not enabled completely.
Another often seen bug, you get to 66%, log off, log in again and it seems to be 100% ful and not greyed out, yet unresponsive. For those with the same bug, just go kill a few low level critters and wait for the “…….. skill unlocked” message to pop up.
