[4.27.2] Can't save any structure

Development Platform & Builds

Hello, for a few weeks I can no longer work on UE 4.27.2 since I have a recurring error that happens to me a lot on Structures.

I currently have a personal pc, a business pc, and a pc from my video game development university.

And in any case, I can’t save variables in a structure.

If I close the file, if I close UE, if I run a simulation, everything will be deleted, even saving.

Here is a log that I was able to recover during a save of a value in a structure.

Solution : Transform is a Structure.

The engine does not like to work on a structure which itself contains other structures, so I deduce that the Transform is a Structure, the same for the class selection.

So use a Simple Location or Rotation instead.
