Cant upgrade to strong heal potion

the strong heal potion is showing red at the alchemist. I am level 55, have 10+million gold, 500+ bundled herb and 45 angelbreath but it still wont let me upgrade.

Looks like you need 50 Angelbreath

ok thanks! I appreciate it! It would be nice to have that indicated in-game as well.

I took the snip from the game, if you’re on PC, you need to right click on the potion to see the cost (dunno why they changed it like that)
