A glitch can be a number of things. For example, if consistant it could indicate a problem with the computer system, or an error in programming in the software. If it happens only once or twice, and there doesn't seem to be a pattern anywhere, then it's just a "something that happened" type event. Mostly glitches can be quirky, funny, annoying, or down right silly.

When trying to collect items, try moving the child around the item until he or she says: "S/He is looking excitedly at everything" then drop them. In the case of mushrooms, wait until they say: "S/he sees a mushroom," then drop them. As for the elders at 50, try upping one of your techs, that should give you a hand.

Blessed be you.
