What the heck??

Weird. Sorry to hear.
If your stand is solid wood I don't think there's a problem other than it's wet. If it was say MDF or something yeah you'd have a problem but 2x4's and stuff .. Speaking from experience anyhow, I can say 2x4's and 2x3's and plywood can get pretty darn wet and there's no structural concern other than maybe screws may start to rust.
