Might have encountered a bug

Was upgrading Hugo potential the one right of his new divine epinany node and click confirmed. It showed the unlocked pop up and used my resources but after that remained lock and I had to respend resources to unlock it again (definately wasn't tripping since first unlock I needed to change my blue rarity green crystals to orange to get enough but second time I needed to convert the special universal gem currency to it instead).

First time experiencing it wished I recorded but it was unexpected.
