When on ground missions against the borg, there is a nasty bug where if one of them infects you, unless you stay facing towards the direction that the borg that infected you was in, it starts getting flanking damage. Regardless if that borg is dead or not. This is a nasty little bug that seriously needs fixing. Why are the nanites or what ever it is they are infecting you with, getting flanking damage?

Bug number 716,614

No offense, but I'm glad I'm not the only one that happened to. It was a surreal situation. I wasn't entirely sure what had happened, or why I was suddenly taking flanking damage.
I thought it was a fluke.
I won't bug this, you appear to have done so already.

I do hope they look into this as it happens very often!
