Gnome classic panels and skins in Gnome 3, problem.

[k441]

Hey there, it's my first post.
So, maybe I should start, rather than give a long introduction about myself ;P.
Yesterday, I moved /home to an USB drive, which is always connected to PC and linked /home/ with /media/(blahblah)/home/. The drive is automounted in fstab by uuid.
Everything worked fine also after many reboots.
However, today I started LM and panels, themes from Gnome classic showed instead of new. I checked at logon screen and GNOME is selected. After reboot it's still the same. Is there any way to revert to the new gnome panel (I'm used to top-left corner), some configuration to change or maybe it's something wrong with /home?

Edit:
What's more, yesterday I installed python-opencl support and it updated initrd and stuff.
