Hello. I play with the version 0.160.2 on windows plateform from steam. I think that I find a bug. In my inventory, the five first top slots contain tools. The sixth top slot is empty. Some other slots are empty, and one contains ten items of "Carburant de fusee solide/explosif" (in french). The steps are the following: I split "Carburant de fusee solide/explosif" in one and nine items; I put the one item in the sixth top slot; I move close from the back of the quad which is equiped with the rocket motor; I press the key "6" to have "Carburant de fusee solide/explosif" in my hands; I do a left click on the quad rocket motor. The results is that I have nothing in my hands and when I press the key "I", nothing shows up (the screen blured and that's all). I reproduced it many times. Hope this helps. Ask my other informations if needed.
