If the "Open Packs" page at https://hivereward.co.uk/limitless/packs/ does not show the page similar to what is displayed below, then the game behaves to you differently. 🤔

If you see the page below (except for the LIMITLESS, STARBITS, SWAP.HIVE, HASHSCORE, and VIP STATUS values which should be different for you), then you can proceed with buying the "Standard Mining Pack" with 500,000 STARBITS by clicking the small yellow "STARBITS" button there, where 500,000 STARBITS will display on the "LIMITLESS FIGHTERS" (which is a display bug). 🤓
