Niagara VectorFields do not function properly since "Fix CPU Access" changes are not persistently saved. After every Editor restart or reopening projects, the Niagara-VectorField driven Emitter and Emitter-Systems are not running and you have to apply the fix again.
This was reported and tested in 4.24.2 (CL-11100242). This was reproduced in 4.23.1 (CL-9631420) and Main 4.25 (CL-11152609)
Results: A fixable, but not saveable CPU access error, that makes it impossible to use VectorFields in Niagara.
Normally you can close the UE4-Editor and everything is saved, but it doesn´t save the fixed CPU access!
Expected: Fix CPU Access is persistently fixed
