I just fixed a bug where upgrades wouldn't work properly...

As always feel free to share feedback/ideas (although probably noone is reading this anyways xD). This will most likely be the last update if nobody shares any kind of whish for more updates. What I mean with this is that if nobody says anything this project will NOT be updated anymore. But I'd still make updates even if it's just for one human beeing on person in this smal yet great comunity.
