My mini was at the airport for 2 days and was still fully intact.

Can you share some context on the problem? Are you new to using this plugin, or have you been using it for a while and now suspect a regression? Was the mini spawned by a plugin or is it a vanilla mini?

Do you have any evidence that this plugin has caused this behavior? The only thing I could think of is that you may have the nodecay permission which would prohibit your mini from decaying at all, regardless of whether it is located near a tool cupboard.
