Since I got my last key, enemy tanks will turn dark blue for a few seconds and shells go thru them. Then the reappear at a different location and still alive. No one else seems to experience this. Could I have a corrupted key download? If so, how to I re-install it.
turn off "Ghosts" mod if you don't want to see enemy at it's last location
It is not the key. Its a new mod called "Ghosts". When enemy tank disappears from view it is leaving its "ghost" at the place where it was spotted last time, so you can try to hit it.
You can disable it in WP settings, but personally I find it very useful.
Aside the autoaim (hoping it will improve, right now it's still inaccurate!), I find this feature the most useful.
I had much damage thanks to that.
Hint: 'ghosts' appear also when they're out of view range but spotted by someone else. If it's not too far from range, it gives a chance to (manually) aim well and have a hit anyway. Try it!
Thanks for your help. My problem is solved:)
