I'm sure you've noticed that the default raid browser (the old one) is now missing a scroll bar, showing only the first 19 players. Apparently its because the scroll frame isn't anchored to anything. The XML sets the anchors, but they disappear for some reason - and I couldn't find why, looking at the code. Setting the anchors manually with /run commands fixes the problem, though:
Did anyone find what's causing the anchors to disappear?
