      Hey there, I’m using 3.0.3f1 from the asset store. When I try to add a Reflected/Faster Versions/Check Function and Check property I’m getting the below error in the editor. Nothing is created. They seem to work when creating action tasks (Execute Function, Get Property, etc.), but the conditional tasks can’t be created. This is happening in both BTs and FSMs.

        Hey,

        Indeed there is a bug. Then I also realized another bug. Both are fixed and I have attached them for you here 🙂

        Let me know if that works for you.

        Thanks!

          I’ve not been able to test it extensively but I did a quick smoke test and I can add the desktop only version of Check Property and Check Function now. Thanks for your quick support. I’ll have more time to play around with it tonight; I’ll let you know if I encounter anymore problems.

          Thanks again, stellar support, as always.
