Hey Jean, just wanted to pipe in and say that I'm loving it so far, but I wanted to point out a bug that no one has mentioned. It seems that some shields do not show up on your character, he performs the animations as normal but the shields are invisible. I've noticed this on the old heater, old round, and some board shields.
I do know for a fact it is this mod because I reverted back to the original 1257 item_kinds and they show up fine. After realizing this, I decided to open up both files in the item editor to find the reason and I can't see why they won't show up.
