Open another existing design from the same directory as first one (this seems to be the differentiator)
[*}FC opens the file in the existing tab, drops the first file and creates a new, empty “Unnamed” document
This only happens if the first document is clean and I don’t change the directory in the file open dialog. It doesn’t seem to matter if one uses the menu File->Open, the tool box button for file open or select one of File->Recent files (assuming it’s in the same directory as the already opened file).
Nope. Seems to work as expected here:

It might be related… If I create a new (empty) project, and then load an existing one, the empty project vanishes (is replaced by opened project). But it’s not buggy, it is only dropped if it’s really empty - if I add a box before opening an existing project, the new project is kept.
No problems here either. Doesit depend on the workbench opened? Do you use start workbench with special actions after loading? You may try resetting your config.

Good call, deleting the .FreeCAD directory indeed solved the problem. I’ve restored all my settings by now (AFAIK) but am not able to reproduce the issue anymore.
