Find a quest/tradeskill that is incomplete.
Do a search of the Velious Beta subforum to see if it has an issue that is already reported and if it was fixed pending update.
If it hasn't, give it a try.
There aren't any patch notes, so you will need to cross reference the date of the last patch with any "fixed" posts.
