AtkAddonControl Send Action && GC Vendor Window

Heya, been messing with GC vendors and such to make it possible to spend seals, but since 3.1 its broke with the method that was being used.

Before we could use

Code:

RaptureAtkUnitManager.GetWindowByName("GrandCompanyExchange").SendAction(2,2,0,1,Slot#);

And it would buy, but using this now we get this happening:



Was wondering if theres something we can do because of the bulk item option now(even single items get this error) or if we could potentially see support for GC vendor?
