We’ve been made aware of some issues with certain block colours since the release this morning.
This is a visual bug client-side, and once we are able to repair it, we will push a fix to address this.
Please note: Any blocks mined in the meantime will keep their intended colour. They haven’t actually changed, they’re merely being displayed incorrectly.
Thanks for your patience!
UPDATE: We have been made aware of some mined blocks disappearing from the inventory once they’ve been gathered. We have now isolated the issue and will be pushing a fix when we can. Thanks all.
