Since you’ve already sent the request to IOI for the issue, then really, there seems to be nothing you can do right now. Sorry. You can either wait for their response, or wait for the next update which may or may not solve it.
Which platform are you on, though? To me, the Dartmoor location works fine on PS4. I know that restoring licenses for owned games sometimes work. But I am not sure about the other platforms.
Also, in addition to opening a ticket, you can post your issue in the thread below. There doesn’t seem to be similar issues reported recently.
