RegDesigns has collapsed. Their web site is gone, and they’ve basically given up. From what I understand from posts on their Discord and speaking to a few other folks, the lead guy in the team basically took the money and ran, leaving the rest of the team with no pay, none of the shared profits from the sales, no access to the online stores selling their wares (he’s still collecting money from sale), etc.
There was a posting on their Discord that the remaining team members were considering a new venture together, but realize how soiled their reputation is now as a result of this scam.
Consider it a loss. It’s not getting fixed. Get the FlyTampa version if you want CYYZ. It’s not as recent, but it’s good, and way better than the default airport.
