Post the best example of a save game showing it happening and we will look into it.
Keep the others handy just in case we need others
So this is a Chinese SU-152? There is only one in the OOB.....actually there is only that one in all the OOB's. The only others are in SPww2 and there are four of them. The only difference is unit class but the MBT Chinese one is an SP gun and that is exactly the type of unit class it should be\
The MBT China OOB has three other units in that UC in the same time period
510 - SU-76M - Available 01/050 to 12/077
521 - SU-122 - Available 01/050 to 12/077
522 - SU-152 - Available 01/050 to 12/077
First off are they appearing under AI control? if yes, set up a test game with nothing but all three types and see if they all act the same way but we really do need the save you have showing this before running guesstests
A screen shot would also be nice if you can manage it.
EDIT the EDIT
I just saw it happen
The Pershing had been in the hex marked AI and I moved it to A
It was hit by B but B has not turned towards A as it should have
