Ok, so I took the plunge and tried out the newly Implemented Hospitaler class. At first I noticed that it's spell progression seemed to require the use of a feat. On further inspection the description of the feats didn't match up with the class description. It stated something to the effect that you will progress in divine spells for all of your levels but 1,5,9(1,5,9 are the levels where bonus feats are given). The class description only described 6 caster level progressions and a dm confirmed only 6 was the intent.
After seeing that I still went ahead hoping at the very least it may glitch in my favor

Instead I received an error stating that I needed to choose a spell progression path and that a dialog would be launched for me to choose. The choice was never given. Print screen attached below.

I do thank the Dm that gave me the delevel but I was hopeful for an xp refund. I lost over 4k xp but a refund of 4k would make me smile. Regardless of refund or not It looks like a fun class to progress and I wish the troubleshooter the best of luck.
To emulate this error I would say choose two classes with divine casting ability before leveling in hospitaler. My level progression was 4 paladin / 5 favored soul before the hospitaler level.
