Bug: SU-152 Swiveling Gun?

[DRG]

EDIT

Don't bother with the save game I found the problem ( Andy guessed correctly it was icon-related in that it was entered into the wrong type of SHP file back in 2015 ) and it will be corrected for the next release whenever that happens

Thank you for your time in duplicating this so quickly, and for your continued efforts in supporting this great game. I have zipped up turns 15 through 20 to help with isolating the problem. I have every turn through 24 if needed.
