Hi there! I actioned a bug report yesterday that sounds very much like your issue.
Thanks to the attached savegame I was able to reproduce the problem.
(In this case it was one of the previous removed tutorial states that wasn't complete, and there was a legacy check in Home Teleport for it. Possibly the account may have started the original Tutorial Island when that was a thing. There was actually a feedback message for why you couldn't Home Teleport, but 15ish years ago the only feedback messaging system was the chat window, and that's hidden on new Tutorial Island, so that feedback wasn't visible. Fixed that too.)
A fix for the described issue is with QA - we're on the knife's edge of the RC build cutoff so cutting it close to make it into Monday's patch notes, but hopefully the following week.
Something that might work for you in the meantime... If you press the Esc key, is there a Skip Tutorial option?
Give that a try and it'll hopefully get you to Burthorpe as if you teleported. (Handily as you're on the very last step of Tutorial Island, you shouldn't miss anything.)
