Fashionista and Explorer are broken because the required items are not in the game.

Fashionista: Collect every ship emblem
The progress bar tells you there are 11 ship emblems total, but you can currently just find 2.
Before Resubmerged there were only 7.

Explorer: Find the chart for every landmark.
Before Resubmerged 4 landmarks were missing charts.
After Resubmerged those landmarks got charts, but others were removed entirely.

To get all the items, you have to downgrade the game to before patch 1.2 (Resubmerged), get all the items from that version, then load your save game into Resubmerged and get the remaining items (or try my save game, see next section).

I don't know how compatible save games are. I did this when I was on the very last quest "Skalle" and had no issues loading my pre-1.2 save game into the Resubmerged version of the game. If this doesn't work for you, try to play to the last quest.

Before going through all the hassle that is this guide, try my save game that got me both achievements. Fashionista should trigger as you load the game and for Explorer I left the last chart in Karl the Slow (sub is in front of it), in case the pickup triggers the achievement.

Download the save game from
https://drive.google.com/open?id=1wWIkoXUwuXlYp3Yx3XyGbhR_jLJuV-kd

Press Win+R and type in
Move the downloaded file to that folder.

Launch the game and hope it works. Good luck!
If it doesn't, feel free to read on and try yourself.

To downgrade the game, follow my other guide here

You'll need a tier 3 sub to be able to enter the Abyssal Trench. Pick the Icer drill one to get around faster.

Then get every single landmark chart you can, i.e. all but the four missing. The charts are usually found in research capsules around landmarks or in chests in the cities.

You need a total of 11 emblems.
There are 7 unique ones and the remaining 4 will be duplicates.
Vendors restock emblems on reloading, so after buying an emblem, undock and move away until you see the "Game Saved" message and reload the last checkpoint.

Notice: Steam progress will not update and you will not trigger the achievement in this version.

Available Emblems

• Mystery 1 - Reinfjord Relic (9120)
  
• House Spirios - Fountain of Honor (9000), House Kuberi (9000), Clifftop Gardens (9000)
  
• Charmed Serpents - House Spirios Adventurers Guild (7700)
  
• Mystery 2 - Spirios Banquet Hall (9000)
  
• Doodle Emblem - Whirlpool Sewer Entrance research capsule (free)

Once you have 11 emblems and all but the 4 missing charts in your inventory, upgrade your game to Resubmerged again, i.e. go to the beta tab and select "None".


Start the game and load your save.

Fashionista will trigger instantly, but for Explorer you need to get Circle of Pillars and Karl the Slow charts. The other two locations (Flood Gate and City of Ice) are inaccessible and the game soft locks if you try to dock there.

When you got the last chart, Explorer will trigger.

If Millionaire didn't trigger for you in Resubmerged, despite having 1m in your inventory, it will in the downgraded version.
You'll just have to farm 1m again.
