In some occurrences the 2s6 will have the acquisition radar “locked” onto something when nothing is locked and in some cases the radar will be pointing towards the turret
First of all, this is not the place to make bug reports, you do it on the bug site. Second of all, isnt that your doing? Im not sure is 2S6 has this optioin, but on some spaa you can change the radar scanned area, to for example looking only to the front(Change radar search mode).
