Not working in Unity 2018.3.7f1 when Scripting Runtime use .Net 4.x

Got error:

When I change to .NET 3.5, it works perfectly. Sorry for my poor English.

Are you using a recent Behavior Designer version? I've tested it with .net 4 and haven't noticed any issues. If you can list the steps to reproduce from a fresh project that would be great.

Hello,

I'm also currently having the same kind of error after upgrading my project to 2019.1 and switching to .Net 4 with the most recent Behavior Designer version. I'm loading my behavior trees at runtime using external behavior.

NullReferenceException: Object reference not set to an instance of an object

Followed by this one :

I remember that version error from awhile ago. You'll want to first ensure that you are running the latest version of Behavior Designer. From there if you can list the steps to reproduce that would be great.

My bad, I did update Behavior Designer to the lastest version but I hadn't done it for the Formations Pack, hence the error.
