Yeah, right now I'm stuck as Chara as I am unable to restore sanity and the instant I respawn I transform into Chara due to having no sanity, and then I can't change back b/c my sanity is unmodifiable as Chara.

i dont think there even should be a count down

i have a reverse problem im stuck as frisk though i always want to be chara even when my sanity is at rock bottom they wont transform. But maybe its cuz of the timer :/

The timer seems really broken. Nobody, including myself, who I have talked to and used this mod with has been able to make the transformation work consistently. It's quite annoying. >.>

I can't transformation into Chara. What i'm need doing??

I'm not entirely sure this is a fix but it worked for me: Go to your mods and change your keybinding for the transformation. If it was z by default try F1, vise versa.
