The Above Bug splat is effectively the only information I can offer at this point as to help out with this problem. I have tried the following; > Joining on Google Chrome > Joining on Firefox > Joining on Microsoft Edge > Clearing My Browser Cache > Disabling Ad-Blocker (and other relevant add-ons) I have no idea how to resolve this at this point, so I'll leave it here and hope you fine people can solve the issue.
