Can't it be saved before the battle? The post that and tell Caliber what battle to start so he could see it. If a fix is to be made, then this would be needed as he has already said he had no time at all to play through the game.
i won't be going back to try and rejigger my options which have been working for over a year to fix one mission. Just leave the options off or don't use the trainer for that one mission
the trainer is hard enough as it is to maintain and update.
Caliber made it very clear that he's not doing anything about this trainer.
