Error when loading plugin

145 VendingManager - Failed to compile: 'VendingMachine' does not contain a definition for 'SetFlag' and no accessible extension method 'SetFlag' accepting a first argument of type 'VendingMachine' could be found (are you missing a using directive or an assembly reference?) | Line: 342, Pos: 20

Also, can't put the new crystal rifles in the vending machines?
