I can't speak for anyone else, but I've used no exploits or even used my RTTS player in DD. All my RTTS progress has been strictly playing RTTS.

Yes, lots of people. Also with fielding.

Note that this is not just you having the issue, tons of people are having it, for RTTS only, as of the last patch. SDS definitely screwed something up, but given that they don't have half a [censored] about RTTS don't expect them to acknowledge it. Your best hope really is just to pray some other change they make in the future will inadvertently fix it as a side effect.

Presumably because he didn't become a first basement until ~97 and the bronze is his rookie card, where he'd have been more a 3rd baseman and occasionally outfielder.

Anytime you go into your Loadout it resets your cosmetic choices back to their default for what you have equipped. The only fix s either to go in and update your appearance every single time you go into your Loadout, or to never go into your loadout after you set them. There is no way to just make it not be coded terribly.

Yes, lots of people are since the most recent update. No known current work around, it's something SDS will have to actually fix (lol).

There is no fix currently, it's happening to a bunch of us.

It's because it does it to save load time. If it rains in the first game it'll always rain for the whole series so it doesn't have to reload the entire stadium. Going back to clubhouse forces it to reload anyway, so if you do that you get another "roll" to see whether or not it is raining.

Seems to have started for a lot of people since the most recent patch, must have been something therein breaking it.

Mine isn't every at bat, but it's frequent enough I can't get all the way through a game. Usually I can get an at bat or maybe two, but if I ever get a fielding event or hit something to the outfield, it crashes. I can play other modes fine (even whole 9 inning games in Player vs CPU in Diamond Dynasty, which I did as a test to see if it was just a time-based thing), so it must be something screwed up with the most recent update inadvertently affecting RTTS.
