To get your pallete LOGCABIN (or ig this is that name)
You need to publish a snowman kit (not castle remix)
Click Create
Choose "Snowman kit"
Change something (doesn't requires)
Save this deck
And publish
That's all
No but all i did was on the kit is just making an actor and scribbling it and published it then i closed castle then reopened castle then i deleted the deck/kit then i got the palette-
