This isn't a disclaimer for the devs as I'm sure both they and community members are very aware of the issue, but if you already have a save file from any previous 0.9 version and intend to load it in the latest archived versions (0.9.g, h, i), you shouldn't bother. Stay on the previous two archived versions for now as you might brick your save. I'm not exaggerating when I say, of all the previous 0.9 builds, this one is probably the most unplayable.

Inventory system is completely bugged and unstable. Items in your inventory will randomly change icons and vanish entirely if you attempt to place them into the drone bag or storage items, breaking the inventory system entirely. Daily task items vanished from the UI when I tried placing them in the drone, and I was unrewarded after sending it back. On a new save, I tried placing a variety of items into the drone, one of them being a beer bottle. Each time I clicked on them to transfer them, they either disappeared from the UI or their icons changed to the beer bottle. Sent the drone back and I was only rewarded for that single beer bottle. Then tried picking up more items but was notified my inventory was full, yet there was no way to drop items and make room because my inventory and hotbar were visibly empty. My player inventory is now full of non-existent items that cannot be seen, used, dropped, or stored away.

I suggest playing the previous build or just waiting for a new one. 0.9.e is buggy but playable.
