Issues are change in supplement and carrier (dates back to fall), trim problems, ? out on pasture.

I don't know how much TC Lite you were feeding so can't guess if either its the sugar/starch difference or the change in mineral levels.  The two supplements have vastly different levels of minerals.  You can't possibly be correctly balancing the same hay switching around between these supplements.

Trim obviously is very important but can't explain things like crest changes.

Even pastures that look "dead" can be very dangerous under the weather conditions you described. The warm spells stimulate stored carbs to break down to sugars.  I've had similar conditions and one of my mares got into trouble.

Stallion:

Same for the stallion plus the dexamethasone is a very important factor.

No reason to stop the Jiaogulan even if it is abscess mobilizing. That's a good thing!  No need to add AAKG unless you see his color has not pinked up from the J. Would also continue the ALCar.
