Error when placing an item from the hideout furniture mod Thread - S.T.A.L.K.E.R. Anomaly mod for S.T.A.L.K.E.R.: Call of Pripyat

An error pops up with the hideout furniture mod when trying to place something from the furniture list. Moreover, the game itself works fine until it touches the aspects of the mod. By the way, the error is here:
