Thanks for reporting this! 👍

This was a tricky one. The tooltip's anchor for items is modified in blizzards function ContainerFrameItemButton_CalculateItemTooltipAnchors() (also mentioned here). Because of the missing tooltip:ClearAllPoints() there the error message you posted will pop up if the tooltip is custom-anchored (e.g. from TipTac).

But the thing is: TipTac only reanchors a tooltip if it is anchored to wow's "default anchor" (typically bottom right of screen). But the item tooltip is anchored to the slot in the bag and I was curious about why it has been reanchored by TipTac in this case.

The reason for this has been hidden action buttons (e.g. for pet actions) which set a default anchor for the GameTooltip but doesn't pop the tooltip up (understandable). After setting the default anchor by hovering over a hidden action button TipTac reanchors the still invisible tooltip. If you move the mouse cursor further to an item in the bag, the additional reanchoring in blizzards function ContainerFrameItemButton_CalculateItemTooltipAnchors() crashes with the mentioned error message.

To sum it all up: I could fix this on TipTac's side to recognize this behaviour and it works fine on my side now. The fix will be included in the next release.
