I haven’t touched Studio in a week so I’m not sure when this issue started happening. Basically; my old IAS MouseButton keycodes stopped working in the live branch, so I checked Studio in order to debug.
The InputBindings that were binded to mouse inputs were set to Unknown and setting them back to their original values(MouseButtonLeft) and publishing still didn’t apply any changes although a part’s position updated normally. Even saving and relaunching the experience reverted the InputBindings to Unknown
Expected behavior
I’ve used IAS since the Client Beta and everything worked fine until now. It sets the MouseInputs to Unknown in every experience. I haven’t even touched the bindings and they were reverted to Unknown.
Regarding the other issue about the new InputBinding’s KeyCode not saving correctly, we couldn’t reproduce this issue. Can you make sure that you are on the latest version of Roblox Studio (version 696) and have no conflicting plugins, then restarting your computer / Studio and save / publish again?
Updating to version 697.x has fixed the KeyCode(MouseButtonLeft specifically!) disappearance, now the KeyCode is saved correctly and doesn’t revert to Unknown.
