Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce GTX 1650 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 456.71

Blender Version
Broken: version: 2.92.0, branch: master, commit date: 2021-02-24 16:25, hash: 02948a2cab
Worked: (newest version of Blender that worked as expected)

Short description of error
After adding Bone constraints around Limit locations and rotations, by seting checkbox true for x,y,z min/max, then object related to this constraints is moving/shifting in uknow value for user (not so far:).

Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]

Add single bone
Select Cube and bone, Parent >
a) Bone ,or
b) Armature deform
Go to Pose mode, select bone, in Bone constraints preproties add Limit locations or rotations
Mark the checkbox true for x,y,z min/max (in my cases for a) Bone moving object, on b) Armature moving bone)

This is working as intended, since you are constraining the bone to 0,0,0 in world space. The bone does not snap to a random place, it snaps to 0,0,0 in world space. You might want to change it to Local Space?

Closing for now, but if something else is happening for you, let me know.

It's this same case like here?
https://developer.blender.org/T88814#1171234
Thats mind, that I wrong understod something here.
I analysing the situation.
https://developer.blender.org/T73933

I should use Custom Space? Right?

What is reason the difference betwen Local space and Global space in Pose mode and Object mode?
Img is from Pose mode, and after G + 2x Y the axes have difrent orientation

Img is Object mode, and after G + 2x Y the axes are parallel not like in Pose.

In boths Axes for objects (orange) are this same.
