Large useful blueprint function library (Morepork Games)

I concur, sample project would be probably most foolproof.
I tried to place it to 4.18 project and got few errors. Then I decidet to read the manual. Made new 4.16.3 project, opened and saved nodes in correct order. Still got errors. Here are the screenshots, hopefully it will help.
Oh, and thank you for this library. Haven’t tried it yet because of the errors but the list of nodes seems super useful. Thanks!
