Hello,
@Dragonvok.
What error are you receiving when trying to do these commands? If you’re typing exactly what you’ve written here:
I’d suggest putting a space between “sell” and the area you want to sell from, for example
/sell all &
/sell hand. If you’ve tried this too, then it may be a global issue, or at least one that affects Skyblock, and if so, it’ll be reported as soon as possible.
