It seems to still be working fine for me. It's difficult to help without more details about precisely what you're doing.
I'm still having this issue:

How to replicate:
1-(Drag & Drop) any project stored on your PC into C3
2-Make any changes
3-Hit Save button
Observed result:
It opens the File Explorer to select where you want to save the file.
Expected result:
To save directly in the same file without asking again where you want to save it.
It used to work fine before and it just recently started to ask where to save the file again. I cannot remember exactly when started as it's been 1 or 2 months at least I think.
This is very dangerous because if you have multiple files in the same folder you can select the wrong file and override it by mistake, as it happened to me a few times because you select quick the file to save to without presting much attention.
I'm currently using the last Version: R338
