I use sublime with remote-sftp on macOS 10.12.6 which is on a standard HFS+ case insensitive volume.
The project I am working on has a layout with kind of an odd structure of packages.
To work on this package I created a HFS+ case sensitive volume and have the project there. I download it using remote-sftp.
This first bug is that the packages can be switched like so:
Which isn't too much of a problem as it saves correctly and doesn't seem to be an issue.
If I close sublime and reopen the project one of the directories will have a spinning circle over it and be empty and the other will still have the files I can edit. To fix this I delete the folder above it 'someorganization' and sync from remote.
My company hasn't given us permission to update to macOS High Sierra which uses the new APFS file system which is case sensitive. I am unsure if this is a problem for that as well. Either way it is kind of an annoying bug for people stuck in an odd legacy situation like I am and hoped maybe someone could take a look.
