fix her up real fast 
i found that if ur bball stop working hit D then tell to gaurd again that also sometimes will make bball retarget as well .
i have got it to get off a MS and target an assualt frig instead lol.
play around that how stuff is found.
if that dont work try changing formations then back to sphere and guard that middle scout again. if that dont work set the ball part to parade with MS then back to sphere and gaurd again. if nothing go to F2 then F3 then F4 maybe it will start up again another thing that might help is hit i for retire then reform sphere and guard again.
