My character randomly loses lycanthropy

[Naghast]

Description of Bug Experienced:
My character, who contracted lycanthropy, just randomly loses it. I don't know what causes it for sure, as i've been assured that my suspicion of it has been fixed,

Steps to reproduce the Bug:

Be me (Kobold, Wizard/monk, 27 wizard / 3 monk split)
Contract lycanthropy
Choose to keep it, do not cure it

Expected Result:
You remain a lycanthrope

Actual Result:
The "Alternate shape" feat randomly vanished. I didn't quite catch when it happened, i just noticed when i was in greyport district house that the feat was simply gone.

Additional Information/Notes
Somewhere along the way, i DID used shapechange spell, shapeshifting into a slaad. I believe that may have given me disease immunity. Is it possible that this, somehow, cured lycanthropy off of me?
That lead may be an incorrect one of course. I don't know. But i may test it, if i get myself afflicted again.

The Slaad observation is a good clue. Likely culprit, I think.

I thought monks cant be werewolfs... I would think it would be that?

That kicks in at monk 5

A fix has been deployed for this, that could be the cause.
Hopefully, this will be the last I hear about it, and I can stop looking at that dumb function.
