-Go to your mod folder
-Unzip Waterfill_0.1.1.zip
-Edit info.json using blocknote
-change "factorio_version": "0.14" to "factorio_version": "0.15"
-Re-zip the whole folder
-And it kinda works :)

Don't even need to re-zip ;)

Oh sweet! I will try this out :-)

Works like charme!

I also tried this on the "Initial Scan" Mod and it works there, too. So thank you very much Palicraft!

Thanks. Btw, change to "0.15" even if using beta 0.16x. "0.16" isn't recognized yet.
Nvm, using "0.15" doesn't work in 0.16x (kinda obvious now haha). I'll post the solution in a new thread.
