I killed the witch as the last bounty and was unable to go back to town to collect the bounty because it says "This ability cannot be used".

# 12 Jan 23, 2014As an update to this, we managed to identify the cause for this issue internally and hope to have a fix in place for the next beta patch. Without going too deep into the nuts and bolts, this was basically the result of the fight not cleaning up properly if Maghda dies in a certain part of her boss arena.
As a workaround for this in the meantime, killing Maghda near the center of the arena should allow you to avoid this bug.

Could you provide a little bit more detail? Where in the arena did you kill Maghda? What class were you playing/what skills were you using? Any specific gear-based build?
Any extra information you could provide could be helpful. Thanks!
# 21 Feb 11, 2014Thanks for the extra info. We are looking into this now.
# 23 Feb 13, 2014A fix went into yesterday's patch that actually should have resolved this. Please feel free to toss up a post here with details if you are still encountering this issue.
