I have yet to see WGT ever replace XPs. Yours would be a first.
Bad news for me. If that's the case, I don't think mine will be different. Sigh
I'm wondering if that bonus on Day 100 -the checkmark-might have had something to do with it.
I can't tell... No clue whatsoever. :-(
Are you keeping track of your actual total in the CC?
Actually I am. They're always being added up correctly as far as I know.
