[4.6.1] All blueprints now broken as of update

Development Programming & Scripting Blueprint

So i updated to 4.6.1 and suddenly everything related to non-UMG blueprints immediately crashes the editor. Trying to open the blueprint list crashes with a blank crash report.

For some reason, opening a UMG widget blueprint first allows me to then open up different blueprints and view the list, however it is less stable too.

Hello Xendran,

I have a few questions for you to help narrow down what issue it is that you are experiencing.

Quick questions:

  1. From what version of the Engine did you update from?
  2. Can you reproduce this issue in a clean project?
  3. If so, could you provide a detail set of steps to reproduce this issue?
  4. If not, could you provide the project that you are working on with the issue?

I upgraded from 4.6.0 to 4.6.1
I can’t reproduce this issue
Is there a way i can private message you the project link?

I’m also having this problem. It seems to happen mainly in my Anim BPs and Xendran’s workaround seems to be the only way I can keep the Persona window open. I’ve also upgraded from 4.6 to 4.6.1 when this started happening.

Hello Xendran,

If you click on my name you will see an email that you can use to send your project so that I can have a closer look at the issue.

I can’t find your email anywhere on the profile page and there’s no hover text O_o. I must be looking in the wrong place

Uh… I had a function called “Use” in an actor blueprint that was never used or placed. I deleted that and all problems are solved…

???

Okay then…

EDIT: And now it’s randomly stopped working again. When i try to make changes to the defaults of the variables in my rMasterSkillBlueprint they keep getting reset (except for one…)

EDIT: Found the problem. I forgot that i had actually made my skills based off of rMasterSkillBlueprint when they should have just been generic actor blueprints. I was messing around adding my masterSkillStruct variables to the rMasterSkillBlueprint and it was causing issues.

solved, see forum thread for details.
