Checked on the dinos on Valguero, fed them, switched 8 hours away from hatching giga egg in the hatchery for a freshly laid one.
Checked on the wyverns on Crystal Isles, gave them some more crystals, looked for supply crates (didn't find anything good).
Worked on my singleplayer base, added more trees to the garden part, some more machicolations to the walls, more crystals to the decorative half of the lake.
Also, since I use Human NPC mod, I built three houses in the part of the base where animals will be kept and crops will be grown. Each house is 2 long, three wide, with a fireplace, a kettle, a table, two chairs, and two beds (in the attic). Sure, humans from that mod aren't advanced enough to make use of all that, but I just want it to look like a small village of sorts, rather than an animal pen.

Finished the machicolations, now I just gotta put all the walled archways, and roof toppers, and a glass buoy after every three rooftoppers, and lanterns above the rest of the gates, and switch all the Legacy CKF keep pieces to obsidian, and then, finally, my base will be done and I'll be able to actually play on that save. It's still a ton of work to do, but way, way less than building the rest of it was.
