Not always being prompted to save work on exit ....
It's something I've mentioned before but have been unable to reproduce
and have doubted my own memory.
However, it seems it is a real issue though reproducing it is tricky.
I went through the process of editing a project extensively and
periodically saving and rendering and saving as an
STL to check some measurements.
I then went through parametrising the code and adding comments but
didn't save the code, just rendered it
and created an STL then closed without a save and it didn't warn me
about the unsaved code and I lost
all the latter changes.
Fortunately because I did a render the backup was up to date :-)
Sorry to say there is definitely a "hole" in there somewhere though it
is very hard to reproduce.
