Mode: Creative Mode: Singleplayer SEED-ID: I will get this later as I have to go somewhere If applicable: MODIFIED PLAYFIELDS: No Reproducibility: Unsure yet Severity: Minor/Major (You can fix the problem by giving yourself the missing items using console) Type: Mining and inventory Loaded my game (using latest experimental) and went mining for missing stuff I needed. The materials shows as being gathered in the UI but when I went back to base there were not there. I could not find them in any inventory that I have including the few vessels I have and their cargo boxes. I have not tried reproducing this but my theory is that you load a new game and just go straight to mine without opening any inventory containers. The act of opening a container or inventory might fix the problem. Come to think of it I have never loaded a game and gone straight mining without loading some kind of inventory menu first to check my inventory. This time I just loaded and went straight away to mine without doing anything else. Perhaps the inventory wasnt instantiated yet and the items werent being saved in your collections? No idea.
