Tried to disinfect the wounds of an other player with alcohol tincture.
i used the option "apply tincture" and the message in the left bottom appeared which said i successfully applied the tincture to my buddy.
The effect: the game gave the disinfectant instead of my friend to myself. Additionaly! Cleaning of wounds make the char sick till the green "looks cleaner" message appears.
Hope this could help! great work! go on!
