The problem arose after the Tanks DLC
When player fired from a Launcher into an enemy tank, I try immediately lay down on the ground to hide self from from the enemy's return fire. The player character of the player lies down and again immediately rises in full height! At this point, I want to break my keyboard, because the my character immediately dies from enemy's return fire.
In order to reproduce this bug Fire Mode from Titan Launcher must be TOP. I tried to reproduce this problem ten times in Direct mode but I never succeeded. As soon as I switch my launcher from Direct mode to Top, I reproduced it the first time! Direct mode is used by default - probably for this reason, many cannot reproduce this problem.
Note! Direct / Top modes were added to Tanks DLC. As I said, the problem initially appeared in the release of Tanks DLC
