Hello. I am seeing this weird error occur, and it just spams the console really badly. I'm pretty sure I have the latest version. Any ideas what could be wrong here?

Hello,
This error is very hard to resolve without having some context; if you could fully stop / start the server so Parkour starts nicely and then see what steps it took to cause the error to start appearing?
If you want to add me on skype: iA5H73Y or join the discord Parkour support server, it will be easier for us to communicate.
Thanks

Okay, thank you. I think it only happens when someone is in a course, but I will look deeper into this in a day or two, as I will have more time. I will reply here or elsewhere with more information. Thank you for the response!

I'm assuming due to the date this was found, there have been several updates addressing bugs since and I have had no further cases of this error, it has been fixed. Please reopen if the problem appears again.
