In the last few days, every time I leave space and come back, my power tray is all messed up. Stuff is rearranged, missing, etc. Yes, the tray is locked. I learned that eons ago. So if it is LOCKED, why doesn't it STAY LOCKED? This is an annoying time sponge.
also, don't use the sort function in your inventory, that will mess up your power trays if you have any items that you can use from your inventory, such as shuttles, the azura comm code, boosts, fireworks, etc.
