BTService Not being able to be made

I cant create a BTService or task in 4.13 but i can in 4.11. I have included the AIModule in the build file. It still is giving me errors. This also happens for BTTask. How do you get around this problem?

Try adding “GameplayTasks” to your project’s Build.cs file as well.

Just tried this and it worked for me in 4.15
