I use TortoiseSVN to commit changes to my addons. I've always updated all the files through that, then logged into WoWAce, project management, then finally Tag Repository.
There are the two boxes, Tag Name, which I filled in "v18.104.22.168" without the quotes. The other box always says "Tagging as %TAGNAME%" which I used to leave alone.
However, now with the new WoWAce site, I tried about 5 times the above procedure. Every time it saw it as Alpha. Finally I decided to try putting "v22.214.171.124" in the first box, and manually changing the second box to say "Tagging as v126.96.36.199" After doing that, it worked perfectly.
Is this a bug? Or was I always supposed to have been changing both boxes?
