System Information
Operating system:Windows 10
Graphics card:RTX 2070

Blender Version
Broken: 3.3.1

This will break:

open the blend file
delete the selected Left bone
select Right bone and symmetrize it
check both Right and Left bones' Transformation constraint setting. Numbers on the Left one will be messed up.

But this works:

delete the selected Left bone
go to pose mode
select the Right bone
go to edit mode again and symmetrize it
Transformation numbers are both fine.

Original description:

When Bones have Transformation constraint and are symmetrized in edit mode, its numbers are symmetrized correctly too.(Map from numbers like Location X min , Location X max and Map to numbers like Location min max etc) but if Transformation constraint's Target and Owner space are set as not Local those numbers are totally messed up and broken.

Will take a look. Meanwhile it's best if you can give us a example file that replicates the issue. The constraint might not be that "intelligent" in my understanding.

Update: Unable to break the value, if you set the value to local space it still works as usual. See attached file.

ok I will upload blend file and check how this glitch happens. wait a moment.

YimingWu changed title from ~~Bone's Transformation constraint numbers won't be symmetrized correctly when its Target and Owner space is not Local.~~ to Bone's Transformation constraint numbers won't be symmetrized correctly.

Can confirm the issue. Looks could be a dirty matrix since once it came back from pose mode it worked as it should.

And I found out Limit location constraint isn't symmetrized correctly.

see this picture. Above constraint setting is , if owner space is set as world, resulted numbers are incorrect.
I need to set it as local to avoid this.

And below is I set owner space as local to avoid above glitch but still result is incorrect. Values are fine but use_min_x and use_max_x state are wrong. I tried other limit constraints and limit rotation and limit scale work fine. only limit location symmetrizing is wrong.

Please fix this. why don't you set owner space as local before symmetrizing?
