Demon Form bugs?

Hello

Dont know if it's intended or not but whenever you're in demon form and interact with anything the game forces you to transform out of demon form which is very annoying. Then you gotta wait 10-20 seconds to transform back. I hope this gets fixed/changed.

Also, Corpsewade decompose doesnt seem to trigger in demon form. Is this because you are sort of flying or is it a bug? Anyway I hope it also gets fixed/changed.

I respec-ed my passive perks today just to shuffle things around and when I went to see how it feels I noticed that when I shifted to demon form any time I tried to cast a spell I would get forced back into human form. The spells I tried include: Frostbolt, Cold Snap, Essence Drain, Contagion, Unearth, Ice Nova, Frost Bomb, and Frost Wall. And as a secondary bug when I tried to reset the ascendency tree passives to lose/readd demon form, I forgot to remove my socketed support gems and they just vanished.
-Edit: I think i found out what happened, the passives I changed to might have lowered my Int score below what Demon Form upgrades my skills to requiring
