I'm also curious about how the yoyo mod and spirit both being installed will ultimately work out and would second the suggestion to add a check to disable dropping of the overlapped yoyos, though I would suggest putting the check in the yoyo mod so spirit drops are the ones that remain.
Also, good job everyone. I was gone for a day and out of three pages there was only about half a page of partially off-topic posts. Cookies all around.
And somewhere over 4,000 hours here, looking at spirit to get me over the 5k mark once it comes out.
