S4 forgets default launcher after reboot

[Theturtguy]

Whenever turn on my s4, it always forgets the default launcher. I am using the stock touchwiz launcher and I'm rooted. Any ideas?

Try to clear all defaults

I found out that the cause was a downloaded launcher that i have moved onto the sd card. Apperantly if you have a launcher on the sd card, it treats it as a newly installed launcher on every reboot, hence asking you to re-select your default home.
