Ok so I'm on PS4 and I woke up to a "Character data has been corrupted" error this morning. I've had these settings since I started the game at 2.0 launch on PS3.

My hotbar setup, each class is set up the same

Hotbar1: main skills
Hotbar2: extra skills
Hotbar3: Gear sets (Dow/Dom)
Hotbar4: Gear Sets (Doh/DoL)
Hotbar8: Used for a few extra skills with R2/L2 combination

The way my bars were set I could toggle with R1 between ONLY hotbar 1 and 2. Also hotbar 8 was different for every class (because of each class's skills and it was not shared by each class) and each class could access hotbar 3/4. (for the purpose of changing classes, 3/4 were the ONLY hotbars that each class shared) Toggling with R1 did not access 3, 4 or 8. I'm pulling my hair out trying to remember how I made this work, I've tried all combinations I can think of between the shared and cross hotbar features but no luck.
