  • Make a Behavior Tree
  • Add a decorator to a node with an Enum condition
  • Go to the Enum and delete a state
  • Go back to the Tree, click on the decorator. Engine will crash

To Fix, read add a state. maybe not a bug (as its expected to crash) but could you guys let it re-adjust the targetted index? i think its the expected behavior.

Hello,

  • Could you please provide the logs located in your project’s Saved->Logs folder?
  • Could you please cause the crash to occur again, and then provide your Machine ID from the Crash Reporter window (assuming that you are getting the CR window pop up) and ensure to hit Send on the report?

Thank you.

hi, in my own project i didnt get the CR window. i reproduced it on a clean 4.11.2 and a 4.12 and the CR did appear. to reproduce on your end you have to select the last enum on the decorator, then delete it (forgot to add this), click on decorator and crash. the machineID is BA6B067D4D3E6C6CCD1AEF923DCA818C. Logs are on my GDrive cause the answerhub doesnt let me upload rars.

Could you please provide the full repro steps for how to reproduce this crash? I haven’t been able to reproduce this as of yet. I’m not sure what you mean by “select the last enum on the decorator, then delete it”.

Please create a clean project, and provide the full steps that you are taking to reproduce the crash in that clean project. Thank you.

select the last enum on the decorator as add a decorator and sect its condition is set to the last enum.
