Default apps won't write to internal storage

Hey there, I'm having a weird issue with apps not being able to write to internal storage. I'm using stock rooted 4.4.2, things work after a hard reset but soon after es file explorer shows that my home directory changed to storage/emulated/legacy instead of /emulated/0 and things just dont work correctly. Eg. Instagram gives me an error, snapchat, Baconreader and imgur also fail to save images. I did use sd write fix, dunno if that could cause any issues.
