[Productions] Moving "Children" of template sequences can overwrite in destination

We've got a live one!
Premiere Pro v25.3.0, working in a Productions environment. MacOS Ventura 13.7.x for all parties affected.

My editorial team loves their templates. Can't live without them.

Here's our standard workflow, which used to work as desired in Premiere 24.6.x (latest LTS release, as of July 23, 2025):

1. Create Template Project containing the desired folder structures and template sequences for edit preparation.
   - Let's call our example "parent" sequence: "Template-Sequence".
2. Save Template Project, and begin "Make a Copy" ops in the production to build out clones of this template for each necessary prep, avoiding Duplicate IDs. As is tradition.
3. While prepping, rename sequences in the new "Copy-of-Template" projects for team sanity and morale.
   - My renamed sequences will be called "Sequence_A", "Sequence_B", etc.
   - Note that I'm not copying the origin sequence, just renaming the sequence in my copied Project.
   - It's quite possible that the child-Sequences now have the same Unique IDs in their respective Project files, but the Project files now have different Unique IDs to avoid "Duplicate IDs" in the production.
4. When preps are complete, Move sequences into a blank/new "Assembly" Project, combining several preps with different names, but identical lineage.
   - They all originated from a copy of the original template, and were renames of the original templatized sequences.

Expected Behavior (and behavior in Pr24.6.x):

Sequences play nicely in the sandbox, and can all be moved out of their template clones and into the new "Assembly" project. No sequences are lost or overwritten, and I can Move "Sequence_A" thru "ZZ" all into the same project.

Actual Behavior (in Pr25.3.0):

Sequences of identical lineage overwrite each other.

If "Sequence_A" is already present in my "Assembly" project, and I try to move in "Sequence_B", Sequence_A disappears. If it is open in the timeline panel, the timeline closes. The same is true in reverse order: Sequence_A will overwrite B in a similar operation.

This can be rolled back with undos, but I must undo in both the source and destination project.
"Which one did I just move from? Crap!"

Is this intended behavior? If so, what feature under the hood does this enable that I'm missing? Is there an option in Premiere's client-side or Production settings to always generate new UIDs when moving sequences between projects?

HELP!
