Auto-target was working fine for the first days I played but now it is broken. I tried resetting the options to defaults, setting all off, setting all on, nothing changes. When I try to click on a target, most of the time it targets it then quickly un-targets again. Tab seems to do nothing. Sometimes right-clicking works, sometimes left-clicking works. Its also doing an annoying thing where I'm trying to look with the mouse and the game pans back to center the default target (typically way-far away). These glitches are making my current task impossible. Any ideas how to fix it? Do I need to reinstall?
