Demon form + vitality support

I had a bug with a previously equipped vitality support on the infernalist demon form skill - game was spamming an 'equip/unequip' sound and not letting me use the skill.

Relogging so the game didn't 'remember' the problem and removing vitality from the links fixed the issue.... but I cannon re-equip it - vitality shows as not compatible with demon form.

Demon Form has vitality support as one of the suggested links when using an uncut support gem, so this is strange.

Also, Demon Form is not showing up in the list of equipped skills when hovering any support gem (not sure if this is new behavior)

Bug appeared with a patch in the last day or so

After some more play time, I am having demon form cancelled when I use almost any spell (except flame wall and frost wall). Maybe game is trying to weapon swap or something? I have been checking all the 'use with weapon set' options for each skill tho.

Also, the SRS aura doesn't seem to be activating for demon form.

Further update:
My weapon set 1 passive skill tree has "Breath of Fire" allocated, which gives +10 Strength.

When I transform into Demon Form, it removes the passive, so any skill with a red support gem socketed does a gear check, figures I don't have enough str to use my gems, and pulls me out of Demon Form... but then can actually cast the spell regularly

Some sort of message when allocating attributes into weapon passives or shapeshifting is prolly a good idea. Will this happen if I get attributes on my weapons which are disabled for transformation? does this sometimes happen for regular weapon swaps or is it just transformation skills?

anyway, I guess not an actual bug. Cheers.

I ran into the same issue that you did. I was wondering why literally anything that had to do with inventory (equipping/unequipping gear, using potions, picking up items) caused a massive stuttering issue and the audio bug with the equip/unequip sound. I then removed Herbalism from Demon Form and the issue went away. However it can't be re-socketed.
