I think this may be a defect
PE Scouts Car and AC not getting Engine damage after 2-3 mines
...
and funny thing is... they still live after 3 mines
and can use fast travel speed to flee "two yellow triangles")
Will attach replay soon (I use so many mines that I will most likely see that "defect" again)
Other player have seen it in their matches, too*
*plz see patch release thread
