Assigned action is lost if file is saved while in NLA tweaking mode on a linked object with linked animation data

What is our bug/priority level for this now that we have it narrowed down to reproduce?

There's some potential for data loss here, with the following situation:

With the help of @dr.sybren I figured out what that sub-track is, and was also able to create a minimal repro.

Assigned action is lost if file is saved while in NLA tweaking mode on a linked object with linked animation data

I've narrowed down the problematic case a bit. This doesn't happen with all rigify rigs. For example, if you create a metarig that only has the super_copy rig type in it, everything works…

Refactor: Bidirectionality on Graph Editor Sliders

Marked for Blender 4.0.

Refactor: Bidirectionality on Graph Editor Sliders

Actually, on second thought (and after talking to Sybren), maybe this should wait until Blender 4.0.

Changing the range of the parameters for these operators is a backwards-incompatible change…

Refactor: Bidirectionality on Graph Editor Sliders

not sure what to do with this patch. it's more of a refactor that changes the range to -1/1 for a few operators

I think it makes sense to merge, since indeed these operators should probably…

Weight paint is broken with Armature Multi Modifier (backport request to 3.3 LTS)

I've tested on the releases since 3.3.x. As noted by @lichtwerk above, the fix is in Blender 3.5. It's also fixed in 3.4. So using any release after 3.3.x doesn't exhibit the bug.

Automatic weights fails with small-scale mesh faces / armatures

I tried a quick fix, which was to basically just do the user workaround I described above, but in code: scale both the mesh and armature up when computing the heat weighting.

That approach does…

Weight paint is broken with Armature Multi Modifier (backport request to 3.3 LTS)

I suspect unless someone specifically asks for a backport, it's probably fine to leave as-is. But I've added it to the Animation & Rigging project board and will ask the module.

Thanks!
