Hi again! I think you're right and the problem is indeed with browser settings. My Edge browser has this bug, I tried Chrome on the same laptop, the bug is still here, I tried Firefox on a different laptop - still positive, then I checked Safari on my iPhone - and the bug is gone! My wild guess is that it has something to do with Autofill option, it's On in all my browsers and is Off in Safari (because I almost never use it lol)
The personality counters bug is still there though. More detailed, it looks like this: if your Compassion is 10, you choose an option which gives +1 to Compassion and open the personality card - Compassion is set to 11, close the card and open it again and Compassion is 12, close, open again - and it's 13 and so on and so on. Basically you can set a personality counter to 100 just by opening and closing the card repeatedly. Hope it helps!
Again - Happy New Year, and stay healthy :)
