File moves rather than copies from a SUBST'd drive

Hello! Using 13.13.9 beta (didnt test in older versions), if I have a split side by side view, one on the C: drive and one on a "SUBST X: C:\TEST" drive, a drag and drop of a file gets MOVED rather than COPIED.

The + icon for COPY correctly shows but an actual move happens.

I'm fully windows 11 updated, and have not tried uninstalling KB5050094 because a quick google didnt quite sound like the issue. I just wanted to confirm its not a bug before trying.

Thanks!

Thanks for reporting this! We'll fix the inconsistency between what the tooltip predicts will happen and what happens, although we plan to keep the default action as Move in this situation. Opus tests the fully resolved path to see if "move via rename" is possible to decide what the default is, which isn't exactly the same as what File Explorer does when faced with subst drives (and possibly junctions/softlinks as well, although I've not checked what current versions of Explorer do with those).
