Known issue. In these instances usually the client and the server instances of Dominions 3 are running on different operating systems and something (possibly random seeds or their interpretation) goes out of whack since the server hosts the turn and the client has to interpret the server output.

Theoretically there should not be a problem, but to isolate this, you would need several different test sets meticulously documented, one set with only Linux instances, one with Windows only, and one with mixed operating systems. If there is only discrepancy with the mixed set, there's little that can be done, or likely little that can be done without massive effort.

And massive effort to fix cosmetic bugs at this stage is rather unlikely.
