BuyEmAll Classic doesn't work with Tukui+AddOnSkins
Tukui+AddOnSkins totally broke BuyEmAll Classic: https://www.curseforge.com/wow/addons/buyemall-classic No error, simply just the default stack buy windows pops up. If I turn off AddOnSkins than BuyEmAll works perfectly. The AddOnSkins' creator suggested to open a ticket for Tukui because he fixed his part:
It's Tukui breaking it. Not AddOnSkins. You will need to open a Ticket for him to protect/enable/disable his alt click buy stack option. From: https://www.tukui.org/forum/viewtopic.php?f=35&t=8318&p=32556#p32525
Only AddonSkins, Tukui and BuyEmAll Classic is enabled, everything else is disabled: it's still the default ui. Also a tried to delete WTF folder to reset all settings and only enable the three mentioned addon. No luck, just the default UI.
