Cannot play because NUMPAD is not supported (left handed)

None of the NUMPAD keys I use to play games are supported, meaning I try to rebind and the game either reverts to the default binding, or leaves it blank. This was not the case in the previous build. The game is unplayable for me due to lack of proper Keyboard Support.

Revert to the old menu.
Right-click the game in Steam, select “Properties”, and in the General tab select “Set Launch Options”. Type “-oldgameui” in the launch config.
