Could not teleport.
You are not allowed into the destination
Could you at least change the error message please? I don't want to know how many potential customers thought "If they don't want our money, I'll just take it elsewhere". They are allowed at their destination. Even more, I want them there. Only a fraction of them reads the blog, most just look for the next classified ad in the list and try to go there instead. And they'll likely remember the name of my place and avoid it from now on, assuming I would have access restrictions in place.
Would it be that hard to replace the error text with something helpful, like the advice to tp to a mainland location and then to the island destination?
