(IAS) InputBindings set to MouseButtons are reset to Unknown randomly

This has happened a few times over the past few days, but it appears that all of my InputBindings that have their KeyCode set to one of the following codes:

Becomes randomly reset to “Unknown”, effectively unbinding that input binding, meaning I have to manually set them back to what they were before.

Still unsure of the exact cause, but it seems to occasionally happen when I return to re-edit the place after having it closed.

This is a duplicate of Input Action Service not detecting mouse inputs in live game

It happened because new keycodes were added and they shifted the value of the mouse keycodes by 8, causing them to become unknown.

Hi,

Thank you for the report. We’re aware of this issue where the MouseLeftButton, MouseMiddleButton, MouseRightButton, and MousePosition keycodes for InputBindings are being set to Unknown. If you currently use these KeyCodes in your experience (by setting the property in the Studio UI, setting KeyCodes in scripts is unaffected), you will need to re-set the KeyCode properties and publish in order for the changes to take effect. We apologize for the inconvenience this has caused.
