First I would like to apologize for my lack of understanding towards this topic. I will be doing my best explaining it and giving you as many repro steps as possible.
Basically this issue has started to happen about 2 or 1 day ago according to reports from my ROBLOX messages.
As you can see in the example gyazo below when you use the driving tool the sensitivity of the mouse is a lot different than before and as you can see it starts to slowly move the position of the mouse from 1 corner to another. You also can’t adjust the camera of the car by using the right click.
The issue happens to all cars on ROBLOX that includes those in places like these
Apocalypse Rising https://www.roblox.com/games/1600503/Apocalypse-Rising
Las Vegas https://www.roblox.com/games/163865146/USA-Las-Vegas
Washington DC https://www.roblox.com/games/102453224/VANILLA-Washington-District-of-Columbia
Many other places with cars are having the same issue I just gave the links to the ones above that I know about.
If your place is having the same issue you might want to post about it too and hopefully this is fixed when they have time. Thanks for your time
