In wc3 team games when your allies leave you can no longer buy items or tavern heroes (and I think mercenaries) for them. It always uses your gold even if the allied hero is the one there by the shop. Is there a way around this for my map? I'd hate to have to create a custom building for every possible neutral building (merc camps, shops, taverns) with custom abilities that manually deduct gold amount from the buying player. If there even is a way to detect the buying/selected player via trigger.
