This happens on GWE, RSN, maybe other routes too. I doesn't seem to happen on CSX. After loading a saved scenario/service, cabin animations become stuck after a few seconds of normal operation. Any user input that triggers cabin animation (moving lever, pressing AWS) will unstuck the animations, but only for a few seconds. Then they will freeze again. Example steps to reproduce: 1. Start any Class 166 service 2. Save 3. Quit to Main Menu 4. Load Last Played 5. Start accelerating the train 6. Wait a few seconds. The speedometer will stop updating. If you had wipers set to continuous, they will stop too. 7. Press 'Q' or perform any other action. The animations will resume for a few seconds. As a bonus, sounds stop updating too. On the screenshot below, you can see that the speedometer is stuck (shows 40 while I'm standing still as indicated on the HUD). I also still hear the sounds of a moving train, the sounds stopped adjusting to train speed when the animations got stuck.
