Player kicked on opening menu

Had a player get kicked with this message as they opened the menu while looking at ceiling.  Second time it happened to them.  They reconnected and were able to use it fine.  Have seen other similar messages in console logs, but couldn't get more info from those folks as to what they were doing at the time.  I haven't been able to replicate it myself.

Could I ask have you added any skins of your own?   

No sir, just the ones that come with the plugin.  I also see that 1.0.4 1.0.5 got released, just grabbed it to update.

I'll keep trying to replicate it on my end also.

Thank you!
