Thanks for letting me know. I should be able to fix the first two issues just fine. I think I know what's going on with Mighty Meek too.
These fixes will be pushed with the next build.
New one: The goblin that trades 75 gold for a passive just gave me a blank passive. A blank spot that just says "Passive <Null>".
Side note, I would like if in these scenarios it showed what passive I'm going to get as I get them, like I do for active abilities.
EDIT: Apparently that screen does, but because it was null I didn't notice :V
