Do you have them set to limited? If so, change to unlimited, save and it should be fixed. You can change it back to limited then adjust the values to where you had them before. A pain, but it works.
After today's patch several of my bindings now have a red circle with exclamation mark in it and they do not function (wing sweep the biggest issue). If I try to change it to keyboard, it has some type of warning like "proxy error" that flashes quickly and does not function. .
Yes, but its not all the time. Someone said when they were testing it seemed when a radar is damaged but not destroyed and it tries to turn on and search for new target that it crashes.
