Hi measuring,
What version of the engine did you convert from? For example did you jump form 4.13 to 4.14. Also would you be fine with uploading a small sample project that has a behavior tree that replicates this issue. (please inlclude any other necessary assets needed for the error).
The DEPRECATED class in that message wasn’t mentioned in the release notes so that may need to be addressed.
Also, another good test would be to make a similar setup in a blank project. If the deprecated warning doesn’t appear then this may be a conversion issue that needs looking into. It would be much easier to determine this if you provide a sample project though.
