There is a new method for adding icons, which is explained in the installationinstructions.txt included with the download. Please refer to that document before asking questions.
We also fixed an issue with the sterile bandages causing accidental bleeding when used.
We are aware of an issue with the boars hitbox not working, and are in the process of fixing it so you can attack them once again.
In other news, we are also going to be adding in a single player version of the mod, as well as a multiplayer version. Some things will be removed, to compensate for our server, since we plan on hosting again once Alpha 13 launches.
For server owners, you no longer have to have your players install the mod to play it! xml files will sync accordingly, although, you will need to have the custom item icons client side in a "Mods" folder to see them. All is explained in the installationinstructions.txt
