I'm having quite a bit of trouble getting these shops to do what I want. I need the shops to sell units only too allies of the owner of the shop selling the items. I've tried adding "Shop Sharing" and "Shop Purchase Item", the same skills team shops like Arcane Vault have. They won't select the unit to add the item too, instead the item is dropped on the ground. Also they seem to not start the "Unit Sells an Item" Trigger which I need. Adding "Select Hero" (or unit) fixes all that but It allows enemies to use the shop.
If I have too I can also set up a unit selling shop since all I really need is for it to sell and set off a trigger.
