Just some feedback:
The update looks good overall. Started a new world as you suggested and things are definitely advancing.
I'm enjoying the upgraded settlement system, it gives the game much more atmosphere, and a new aspect of strategy to the game.
I'm enjoying how main map missions, secret missions, and stashes now have distinct purposes.
I'm enjoying that another mystery is available, can't get to the highlands yet, but it should be better than getting clues saying how bad the world currently is.
Now for the things I'm not a fan of:
Concerning main-map missions, I approve of the current system of handing out spells for players on their first continent, but I feel that beyond the first continent it is too easy of a system to grind out spells. The only time you need to venture out to make spells is to construct your rare or legendary spells, dubbing down the point of exploring for resources.
For settlement missions, I feel that destroying ice pirates should take three or more successes to get rid of them, it's too insignificant of a threat otherwise.
Seeing the 1.116 release notes, I don't agree with making mysteries a 100% bonus to the secret mission system. It ruins the mystery and feel of finding out what happened to the world and instead tacks it on to grinding out building technology. I'd suggest making a purchasable item from the store that will place a mission on the world map randomly that gives you a clue (I'd make it cost more than just shards. I just found out that linen exists, maybe make that a part of the cost? Don't think it's used anywhere else. Make tapestries to resonate with the spirits of the dead! Or something
)
Anyway to summarize, great job and keep it up.
