Evening Spiel, or morning for you perhaps..
Found another mod that doesn't play nice with the buttonbag,

But instead of having a duplicate button like Fishingbuddy, or a pingponging one like GEM this one keeps sitting stubbornly at the minimap.
No hurry at fixing or even looking at it, for such a big button it took me a day or 2 for even noticing it.. just a FYI.
