zoozilla: I've got a problem in the Mayan temple section of Pandora Directive. When I use the matchbox to light the spear to kill the wasps in one of the rooms, the matchbox stays in my inventory and replaces another item in my inventory as well. "Matchbox" appears twice in the inventory list, an there are two icons for it.

So far, it's replaced the black dagger and the jackknife, both of which I need to progress through the game. If anyone has any suggestions or possible solutions, I'd really appreciate it.

Longcat: this happened to me while playing the gog version as well actually. I restored a previous save, did things again in a different order and it didn't occur the second time.
