How can I drain a lake of Xenomass?
For the quest Cultural Burden, I have been tasked to "Drain the Xenomass lake at
the crash site."
However, I've no idea how to do that. Any improvement a worker can apply produces a warning that doing so will fail the quest, as does attempting to
build an expedition.
What must I do to progress in this quest?
Solution 1:
Go to the Xenomass lake using any unit. There will be an additional button on the unit's actions bar, labeled "Drain Xenomass". It's on the right end of the bar and looks like a puddle of bubbling liquid.
