The Black Shuck is broken. Whenever you click it, it seems to add another instance of its cost.

The Director's Cut and Self-Defense Sugar don't have a "no containment cost" tooltip as I have seen a few others have.

I will continue to update this as I find them.

Not sure what you mean with Black Shuck, I'll check it if I get the chance. As for tooltips, they vary in contents deliberately, though that is something I will be changing.

Just wanted to follow up with you again to say that I'm working on a total rewrite of SCP Clicker and it will be a while before the next release, but it should be much improved as well when it's ready.
