I have tried fiddling with settings, tried right-clicking, tried deleting other TARDISes that may have causes issues, I've tried different character models, I looked through discussions to see if other people had the same issue and someone said they did but they just had to go to option and it fixed it but it kept happening to them. I tried going to options but that still didn't work for me. I even uninstalled GMod and reinstalled it and it briefly solved the issue but then when I reloaded the game the issue was immediately back. No matter what exterior I click on, the default blue Smith-Capaldi TARDIS spawns whilst telling me it's the extension I clicked on. And even the default TARDIS is broken. It can fly and cloak and demat and remat and all that but when it's broken and needs to self-repair, it will tell me to vacate and then it does nothing... the doors don't even close. It just sits there. The same for the redecoration option. The notification pops up in the corner telling me to vacate but the power stays on and the TARDIS just sits there. And the chameleon circuit is broken too. It sort of changes the exterior but keeps the police box doors and then when I materialise somewhere else, the doors deposit me in the same area as the place that I left. It has been like this for months and I just sort of tolerated it because I don't mind that interior and it mostly works but stuck with the same broken exterior and interior for months on end when I used to be able to utilise all of the TARDIS extensions has got so dry now.
