I really enjoy this mod, thanks for your work!
I managed to complete the "Dark Factorian Dungeon" quest by getting one dungeon chest from a dungeon, placing it on my territory, then picking it up.
Then I got "Lazy Looter" the same way using a bot.
It seems to also work for the dungeon quests of other planets, even with a chest sourced from Nauvis.
Maybe you should change the dungeon quests from getting all the chests to get a single chest from a dungeon (Of course, this does not solve the bug that the chest is reusable for the quests). The dungeons are fun at the start, but soon they became grindy. The loot still probably worth to go for more chests.
