Description:

Compiling a particular blueprint and then attempting to follow “TargetArray is undetermined” causes a crash. I’m able to reproduce this every time with steps outlined below. After encountering crash, I reverted to my last restore point and was able to reliably reproduce this crash.

Steps to reproduce:

  1. Download archive of project at restore point immediately before crash: https://s3.amazonaws.com/limbx/crashlog/LimbxFlyer.crash.1404329500.
  2. Do not restore previously open assets
  3. Double click RingManager blueprint in Content Browser
  4. Open event graph and click “compile”
  5. Compilation will fail and error console will open. Click on ‘… “TargetArray” is undetermined’ error message.
  6. editor will crash.
  7. Unzip and replace working directory with archive to reproduce this crash.

Hey piinecone,

I was able to duplicate this crash, and I’ll be writing up a report in our system for it. Once I get some information as to cause, I’ll update you. Thanks for detailed report!

I just tested this in our internal build, and after converting project this crash no longer occurs. I suspect some changes to engine have fixed this particular crash, and once we release 4.3 you shouldn’t run into issue anymore. There will be a preview 4.3 build available sometime next week, and I will let you know how to get ahold of it if you want to try it out.
