/ is the default directory if you want to save a file in gedit. Is it intended? I thought /home should be the default one.
Last time an issue like this happened for me (on another distro), I had done something to make my user's home directory inaccessible. This could be done by deleting the folder, a separate /home partition not being mounted, bad permissions settings, etc. Is it possible anything like that could be the problem?
Went back and tried to reproduce this. Was able to reproduce when trying to save a new file. Existing files default the save directory to the one they are currently located in, as expected. New files default to /.
I'm using a separate home partition with a directory specifically for Solus. Directory permissions: drwxr-xr-x. Owner and group are both michael.
