Most of the resources will fill back up in time, so I don't view that as an insurmountable problem. The mithril is more of an issue, because it's such a rare drop. And perhaps the jewels, but they drop pretty frequently. It would take 3-4 days to get back to normal (full) on jewels and silver.
Maybe people could list the resources they used during the error portion, so we can get an idea of what people actually used? That would give TL some factual info to help decide how to handle this. I'm thinking we need to collect some facts now.
But then again, I could be wrong. It's happened before. Well, once.
