So what exactly is being done when you see the text overlap?
Just regular cursor scrolling through the item list.
I must unfortunately report some additional visual corruption in the description field of relic items, in the item list. The "Sniper Sight" relic sometimes overwrites the description text twice, and the first letter of certain relic descriptions is sometimes overwritten by another unrelated letter. Nothing game-breaking, but reporting these is the least I can do to support this wonderful project.
Edit: Tintinabell is originally introduced as "Cat's Bell" when first obtained from the wounded soldier, after sending his letters to his lovely Lola.
