TBH I got the same issue while trying out the v16 source. I checked up the function and it triggers if flyff.a/.b isn't the same. However I'm 100% sure they're the same and are placed correctly. Currently, I suspect it's a database error. Try different databases.

I'm so stupid. I thought you could reshack the version, but it obviously needs to be changed in the source as well. Big bummer LOL.
