The plugin has been working fine for the first week we were using it, but now the following error is occuring when trying to teleport to a home invite:

It does not seem to occur for all home invites.

I have also seen this error occuring as well, not sure if it's related:

Any assistance in resolving this issue would be appreciated.

Same thing happened to me today. But it works on all player exept one recently registered player.... When someone tries to invite him this error popups in console and in chat plugin says "internal error please contact admin"
