Access None errors creating log spam in user's project when he is editing the BP. This causes a gradual, but significant, increase in the Editor's memory usage.
It appears to occur with a a reference to character movement in the player controller event graph. PIE seems to resolve the log spam, but I think it's only because there is actually a character to reference instead of returning a null value. Adding an ?IsValid check in front of the reference also resolves the log spam when editing the BP.
User's project can be found here: [Link Removed]
NOTE: There will be some errors when loading this project as the user had to remove some content to upload it, but the error still reproduces
See attached image for the location of IsValid to resolve the log spam
1. Open the project linked in the description
2. Open the output log
3. Find the MyController BP and open it
4. Check the log
Result: Log is being spammed with an Access None error that keeps going until you PIE or close the BP editor
