Hey,
thank you for your feedback, I copied it in my /todo things.
Indeed, sometimes that error shows up in logs and it was an issue of some enchantments not having an entry in the game, like "Potion of Cure Poison" (the "cure condition" enchantment was the issue here).
I added them all so these error logs shouldn't be shown anymore.
I uploaded already the newer update (20240125).
Regarding the "Short blade" skill, I checked it again and it seems there's no issue. What kind of short blade you weren't allowed to equip? Usually, when you can't equip an item, a "reason" shows up in message bar (above characters).
You can find the criteria for all skills under "7.4 Skills" in the provided RULEBOOK.pdf
I will consider some of your nice ideas as the content keeps building up :)
Thanks for the feedback!
