I think that a Spyglass and a Solar Still do not work.
Seawater is not yet purified even if it passes more than two days.
In 1.6, It was purified in the evening if I put seawater in morning.
However, this may be adjustment or specification or misunderstanding.
We do not understand a bug or the specifications.
The mini-map does not change even if I use the spyglass in “mid day”.
I think of Quickslot and Zoom-in/out not to matter…
