Sorry you are having this problem :frowning: Could you give some more details on how you tried to create this var, if it had a particular name or type, what type of Blueprint you were in etc? Is this easy to repro?

I tried redoing the Door Blueprint tutorial following the steps.

Just happened again.

This time. I created a variable. Throw it in. used it… saved( I swear I did )… realize no changes happened in-game. Then I go back to the blueprint. Changes are gone. Re-created the same variable with the same name. And then it happened.
I did notice that right before it happened, when I click new variable button, It didn’t ask me what type, it skipped and directly created the variable ( supposedly with no type ). At this point, selecting the variable shows empty property, but editor is still usable , until I decided to click around and the error pop out. I noticed that the var property seems to be showing up blank ( check the screenshot ) when this is about to happen.

In all 3 instances, it happened in Event Graph of blueprint object.

Irony of the Irony. When I re-opened the editor. The changes were back on.

Did you have Blueprints with the same name in different locations? We fixed a bug related to that recently that may be what you were seeing.

6

Just checked… nope. no blueprint of the same name

7

We have fixed several issues with variables shadowing inherited variables etc for the next beta. When it comes out, please let us know if you are still seeing this issue!
