well. first of all it does happen only with resources. i didnt try branches and twigs but long/short logs and grass cause the bug for sure.
- if i rightclick the resources it can happen that they go to the crafting window. thats how it should be, BUT it can happen that in the very short time while i move my mouse from the resources slot ( my back ) to the "craft" button, they dissapear in the craftwindow.
- its random. sometimes you are able to craft 4 grass in a row, sometimes it stops you after just 1. as i said its random but it happens a lot when i crafted 3 grass and want to start the 4th
- i do craft always 4 grass in a row, i do not craft / move them in the crafting window 1 by 1.
- i do not use any other actions, i do not even move my mouse. its the same way i craft since years. no key which cancel the action so far.
- what happens is not like you stop crafting, lets say you jump, use H-key or ESC, couz then the grass which was not crafted yet will stay in the crafting slot, the resources simply dissapear without any reason and its just logical that the game tells you that you miss items to craft.
i'll ask kyosa again to reproduce it and fraps it as well.
