When a Mutant find an artifact, he can keep it for himself,OR leave it in the sanctuary.
In this second case, the artifact benefit to all the People (NDev Bonus).
My question is, what happens if the artefact is stolen? Does the Ndev decrease (in the same way he decrease when a project is destroyed)?
Further, what if a mutant need it for some days, an expedition for example... Does the NDev decrease or is it considered always in the community?
Rules suggest that the NDev decrease only when the Artifact is NO MORE in the community (it's to say : the People can no more use it).
But in this case, as a mutant, I always leave it in the sanctuary, and use it when I need... then I benefit both effects : NDev, and using it.
Sure, leaving it is quite a risk... but it's a low risk, regarding the benefits...
Then I think I misunderstood something... Don't you think?
