Bulk buying should now be fixed

Had wanted to upload this sooner, but Itch broke on me so I wasn't able to do anything, but seems like it's working now, so the fixed update should now be uploaded.

It took a while, but I believe I've now finally fixed the bulk buying fully, there's probably something that's slipped between the cracks but I couldn't find any way to break the actual points and such when testing, try as I might, so hopefully that means it is all good. That being said, regrettably I wasn't able to get the preview values to function consistently. Tried everything I could think of, and sadly nothing worked better than what is currently there. Hopefully I'll have some epiphany in the future and be able to make that look all nice and accurate, but for now, the system being functional is going to have to do, and I'll get back to working on the next layer of prestige.
