Fixed the crashing bugsgrape

It technically doesn't crash, but for some reason the GUI is frozen
immediately on startup and is completely unresponsive. It may have
something to do with calling some function in them multiple times over
and over again but I don't know. I added some debugging text with
comments next to them as "eat this note". Those lines can be removed
with no concequences.
