Multiple chances to get an item

[miodhchion]

I'm using version 2.10 and working on a quest where I have maps that you can't return to once you complete them. I'd like to give the player an opportunity to get items he may have missed on those maps, but I don't want it to be possible to get them twice.

It seems like it should be possible to use triggers to make an item only appear in one place if the player hasn't already gotten it in another, but I haven't been able to figure out how.

Has anyone done this? Or found another solution to that problem?

Thanks,

It would probably be way too much work to use triggers to make the item dissapear in another place by taking the item in the previous location. Instead, you should probably make the item required to get in that map to continue. Alternatively, you could put the same item in a shop later on. None of this would work with items like pieces of heart, however.
