So, I understand that, last time I filed a question about this, it was said that when upgrading, the price was just auto deducted with the current rank, and upgrades were removed. Now, I'm not sure if this is true, as I was told by @Jim Wilson and saw myself when proceeding to the buycraft page that there was no deduction despite the fact that I am already diamond. This makes it an extra $40, and I was told before by @EA_Sharks that it should be deducted? I don't know if this simply doesn't work for skyblock or if it doesn't work in general. Thanks for taking time to read this!
Go into the Squadcraft store, click on the 'power off' type windows button in the top right of the screen. Then repeat the whole process again, sub-server, IGN. Then the right prices should pop up for you. I got the problem too when I bought myself and Fastened emerald, but this fixed it.
I attempted to do this, yet it still shows emerald as $100 It's gotta be something skyblock donate page specific because it recognizes that I already have diamond and won't let me purchase it.
This guy has necroposted on several threads and has been warned lots of times. Pretty sure he has other things on his mind.
