When the user disables the tooltip in the options, the TSM hook from BreedTooltips.lua remains "active", which means TSM cannot display its tooltip (due to the now missing BPBID tooltip frame).

For a possible solution (resetting the parent frame for TSM), see: Xruptor/BagSync#231 (comment)

This is a duplicate of https://www.curseforge.com/wow/addons/battle_pet_breedid/issues/24. Sorry, I have only seen afterwards that you have Issues on Github.

Another issue I noticed with TSM enabled is that on first pet hover after a reload or login no tooltip shows at all but if you move mouse out and in again, then it will show.. but yeah TSM tooltip is broken still if you have the BPBID tooltips disabled
