Good news, she hasn't displayed any weird/overly reactive behavior since my last post. She went into shed almost immediately (probably her body trying to heal herself) so all she did was hide, then after she shed I fed her so she spent a couple days hiding and digesting, and now it's been a couple days of her exploring as usual and she seems to be back to normal. Assuming the behavior doesn't come back, I'm willing to write this off as some bizarre fluke since I really can't think of what would have caused it.
