Since the last update, I've had two characters so far who have experienced this issue. As far as I can tell it seems to be associated with reagents possibly. This just happened on my JC after crafting two gems;

And here is my enchanter's reagent bank, displaying the same visual issue;

In both cases, when opening my bags (or reagent bank in the case of my enchanter) the following error is output ;

Error in AdiBags: Interface\AddOns\AdiBags\widgets\ContainerFrame.lua:1008: AdiBagsSection13:SetPoint(): AdiBagsSection7 is dependent on this -- details: [Error 0000021C5A996B20]

Aha! Thanks for the tip to prevent it.

yup I got that error on my NE priest like 5 times. I was coming here to report the bug, but looks like I don't have to.

This is a known issue that I thought I had resolved in the dev version, but I absolutely just ran into it again last night. I'll take a look at it some more, but if I can't fix the current iteration of the code, I'll likely rewrite this part of AdiBags from scratch.

Also, you can prevent this bug from happening for the moment by disabling the compact layout option.

Is this still occurring?
