I got a turntable to work in TS2022. The turntable I'm using is "VR 70ft BG Hand Operated Turntable" <kuid2:1854:31520:1> by VicTrainz.
1. Edit in Surveyor Classic
2. Delete turntable
3. Move all the stubs and roundhouse sections back a little bit
4. Place the turntable again
5. Rotate the turntable 180 degrees
6. Re-connect all the stubs and roundhouse sections
I have no idea why it worked, and I have no idea if it'll work for anyone else. But I thought I'd share it here in case it helps someone else.
