My bad, I forgot to mention that you will have to change the "compatible_versions[]: "1.49.*"" string in manifest.sii to say 1.50/your current version instead of 1.49.
Hey there, sorry for the month-late reply :P
The mod should work in 1.50, but it will be pretty redundant soon, since SCS has added the FlowBelow kit to the Anthem themselves in the 1.51 beta.
