The link to Wizardry that appears in the discoveries section is broken. Opens a tab in the browser that leads to:

https://gog.comgame/wizardry_proving_grounds_of_the_mad_overlord

But the browser says that it cannot be opened.

But the real problem is that when you close the tab, it opens again in a loop. I had to forcefully close the browser and GOG Galaxy to stop the cycle.

its just a spelling mistake and there should be a / between .com and game

i.e, https://www.gog.com/en/game/wizardry_proving_grounds_of_the_mad_overlord

note the en part isn't actually needed but i'm old school
