The new update introduced scaling hitpoints on all mined resources based on the planets tier. If you’re mining on a middle world (which I’m assuming based on the gleam vein) then you will see something like a 30% increase to block hit points. This is intended to add scaling difficulty as you progress through the boundless universe. If you’re simply seeking basic materials like stone, wood, soft coal, copper, iron, etc., then you’re incentivized to mine on a starter world instead. There is some ongoing discussion on how to better make mining on higher tier worlds worth the extra investment in tool durability and time, and I would recommend checking out the thread discussion on that.
Animals as well have had their hp buffed and their behavior modified. You should be seeing a “threat” phase before they become aggressive, giving you a brief chance to back away from a fight. Look and listen for the various threat displays from creatures around you.
Both of these changes are made with the interest of progression and scaling difficulty in mind, a fine balancing act that being fine tuned and tweeked frequently. Keep that in mind, and please leave feedback and suggestions based on your experiences.
