分别是4.2.09跟4.2.11的物理约束默认顺序，4.2.09默认从小到大排布，4.2.11默认从大到小排布，导致物理失效
4.2.11物理约束默认顺序出错，导出物理失效
4.2.14依然存在这个问题
This issue has indeed been fixed. However, the fixed version will be released after the other fixes have been completed, so we hope you will wait a while before releasing it. (The fix is not in the just released 4.2.15-beta, but will be in the 4.2.16-beta).
Sorry what is this problem? Please describe how we can see the problem. It's hard to understand from screenshots. It's best to use this template:
- What actions to take
- What do you expect to see
- What do you actually see instead
Ahh, I missed that this was about resetting the constraint order. We have redone the logic for that in 4.3.25-beta. It should be much smarter, but maybe it is wrong. It no longer deletes all your folders and you can sort a single folder.
Here's a project making it easier to reproduce, in case it comes up again:
constraint-order.spine
679B
It seems the insert position when a new constraint is created is correct, but clicking the Sort button is reversed, but only for physics constraints. We've fixed this in 4.3.26-beta! 
Yes, that is the meaning of beta! 
We have to make a lot of changes for new features and all kinds of things can break. For constraint order, we did a lot of work on it, but missed that physics weren't sorted correctly (all other constraints are correct). Also we are now much more efficient when sliders have 0 mix (described here), but that change affected many things.
We'll release 4.3.26-beta now and hopefully most issues are fixed. The idea is that we fix things rapidly so fewer users suffer from a single issue. Compare to Adobe or other big companies, where if they have a bug it will be months (or never) that it is fixed, so eventually every user suffers every bug.
Your reports are extremely helpful in finding and fixing bugs quickly. We really appreciate your effort!
