No one knows the exact cause of this error, but it's common enough to be annoying and the only fix is to actually make the game re-save your .2h file. As in either "Redo turn from start" or go into your turn, change something, and hit end turn. Just hitting end turn might work, but better be safe.

Apparently the server still has the old turn files there when a rollback is performed, though it indicates that everyone needs to resend their turn files.
