Just tried it. With and without StatBlockCore.
It was either a flat rectangle or stack on top of one another. I couldn't get the block to update correctly either. I'll take another whack at it after sleep.
P.S. -
I'm looking for something to fill the area directly under the four buttons to the right of the minimap. Mainly with current SP, Haste, Crit, Latency and hopefully with xp/rep and durability.
P.P.S. - Sorry if I sound a bit confusing. Long raid night and I'm a bit muddled. I'll make more sense in the morning.
