Something about units and stocks.

[RammaLammaDing]

I have this unit which is sold from a tavern, but i only want it to be sold once and never again, how is this possible? the "Stock - Replenish Interval" doesn't go further than 3600 seconds.

Remove unit from neutral buildings via the action:

• Neutral Building - Remove UnitType from all marketplaces

--donut3.5--

Does this work even if the seller isn't a building and isn't neutral?

 

[RammaLammaDing]

• Sell
• Unit - A unit Sells a unit
• (Unit-type of (Sold unit)) Equal to Test
• Neutral Building - Remove Test from (Selling Unit)

The seller is a unit and it has the Sell Units ability but still it doesn't work? Can anyone help?
