Problem: Renaming event = file disconnected

Hello everyone,

in Cubase 12 Pro I renamed a file name here:

Then I opened Cubase & the Project another day:
“2 files are missing” or a similar message appears.

Here the Pool and empty events:

Can’t I rename files and Cubase does the rest in the background?
I still see and have the the files in the Project folder ----> luuuucky !
The actual files got renamed as I wanted. But somehow Cubase does not see them anymore.

Ouké, in the Pool I searched for the new filenames and tadaa it all works fine again. The events showing the waves and all.

Still: why the hassle? This feels like a bug, right?
Any comments and ideas welcome - thank you!

Anyone had the same problem?
