RPC Error in RPC_WantsMount

This one has hit us twice so far.
It only affected mymini and the problem went away when we reloaded the plugin.

I suppose there is more to this error because I don't see anything directly from the plugin.  Do you know what was being done that may have triggered it (/gmini, disconnected player, etc.) ?

No idea, it seemed completely random. I have a few plugins that effect the mini: MinicopterStorage, MiniPlate, and MiniTrails.
I assumed it was a plugin conflict so I switched to the umod version (SpawnMini) and so far I haven't had a problem.

Changed Status from Pending to Closed
