Need help with Achievements

[Toast]

I'm at 80/84 feats right now. I have completed 95% of the game. I'm stuck on these achievements below:

Waterproof - Build on top of every water tile

Most of my islands are covered in bridges. Not a single water tile (excluding oil rigs, and lighthosuses), not even under the fountain, crystal mine or some temples. I checked multiple times across the islands.

I don't want to have to go through breaking every single bridge and filling it with a landfill, it's tedious. I really want to finish all my achievements, so are there any suggestions as to how I can finish this achievement?

I went through other people's discussions and I tried breaking a bridge and replacing it with a landfill, it did not trigger the achievement. Most people had the achievement triggered by only doing that.

Most of the time, the feat bar on this achievement tends to be full, it just doesn't trigger the achievement for some reason?

Daredevil - Dodge a lethal attack

I honestly don't know how to get this achievement done. I searched the web nothing came up. I finished all my dungeons. I went back to the Fire Temple, to fight the boss again, it didn't seem to attempt any attacks on me? All it did was spawn little mobs to attack me.

Help?

Treasure Master - Open all big treasure chests

I currently have 40/46 treasures found. As you know with 95% of the achievements done, I finished all NPC quests, puzzles, temples/dungeons, museum bundles, and whatnot.

I just want to know how to get the rest of the treasures? I couldn't find it on the web.

Completionist - Achieve every other feat

I cannot complete this achievement without the 3 above achievements, so please help.

The daredevil is easy all you got to do is bomb your self down to one hp and then go to slime and wait for them to jump on you and hopfully you dodge the attack. you cant get dodge from boots and skills

The waterproof I don´t know I have problem with that one as well.
The treasure Master is weird why it doesn´t trigger. Have you find all the secret rooms (think its about 12 secret room don´t know for certain)? Have you unlocked every island and done every puzzle on those islands?

I'm going to give this a try, thank you.

Yes, I finished every single achievement in this game except for the 3 above.

Oil rigs need a 4x4 area to be built, but after building them, you can fill in 4 of those spaces with landfill. Maybe that counts towards the feat?

If you don't have the endgame dig thing, make sure not to destroy the rig after making it 3x4, because you won't be able to build it in the same spot again.
