Well I lost water storage. Turns out festive creepers throw TNT even when you are right next to them. Also turns out that three of them tend to be destructive. Also, turns out that all three were right below the spatial drive thingie. I suggest that the dungeon right underneath the base be edited so there isn't anything below you. I lost a lot from the TNT including two ethereal glass, a dense power cell, some of the spatial pylons, and I got an energy acceptor from the ruins, but I have no idea how to use it,
The dungeon below has no spawners active, I suggest using your sapling storage so you can get your mineral water, then dig down and hit a run all the mobs and spam torches, once you light up the first floor mobs wont bother you plus its a good way to level your weapons and pick early.
