I have a bug in which sometimes the build hotkeys for particular fabbers stop working. I'm using the default hotkeys rather than HotBuild, I know this probably makes me a bad person, but I've got used to the default system. I never had this issue before Titans, so I'm not sure if it is new or what. In one game I could no longer use hotkeys on naval fabbers, and in a more recent game I lost vehicle fabber hotkeys in the middle of a game. At the start of the game the hotkeys were working, and all of a sudden they weren't. I can't find this issue anywhere, as I'm probably the only one not using HotBuild.
