I'm curious about this one. When I play with my friend he often complains about this problem and I never get it so we were writing it off to lag or something.
But the difference is he plays exclusively UEF where as I mainly play Cybran. Everyone here that is mentioning it is also playing UEF.
@Melanol could you see if you can reproduce it on FAF Beta? It hasn't been updated the past months

@jip Tested in beta. No walking in circles.
Same map, UEF ACU vs a line of medusas. Default: circles; beta: no circles.
@tatsu thank you for reporting, @relentless thank you for the UEF suggestion and @Melanol thank you for taking the time to sand box it. I'll hot fix this tomorrow evening

I came on here specifically for this. I notice every time I am in close range with enemy units really counting on the Overcharge my commander starts doing the old circle back retreat instead of shooting the Overcharge. It works half the time. I even rewrote the key from O to Q thinking I was fat fingering the O and hitting the P. I also do play UEF just because I am a moron and it takes me to long to figure out the other races.
I do not have time to do a hotfix this weekend; the fix is available on the FAF Develop game type for those that keep running into this problem. Another solution is to always get the gun upgrade .
I'll try to hotfix next week.
