I remember that in original Fallouts stealing/lockpicking gave some experience. Is it true for Tactics? I tried stealing and lockpicking but it gave me nothing with a single strange exception: When I use my lockpick skill on an open container that was previously locked, I can lock it again, which gives me 15 exp. Then I can unlock it once more, for another portion of 15 experience. I can repeat this process indefinitely, it seems. I don't get it. Is this a bug?
