When I try to enter my house, it doesn't let me in. It doesn't show the buy menu either, and I still see it in my owned houses, so it's not like I no longer own it for some reason. I've tried right clicking, left clicking, shift right and left clicking, relogging, using a different mouse, and just about everything under the sun. This started happening a while ago, before I had a leave of absence from GTM for a while, and I had hoped that when I got back, it would be fixed, but no luck. Here is screenshot of my houses list, with the house I cannot enter. Hope it helps. If there is any other information I can provide that would be of use, let me know and I will gladly do so.
