Created a new level and added a terrain. Added grass foliage and enabled density scaling located in the grass foliage settings mode. After placing foliage on terrain, the editor crashes.
This is not occurring in 5.0 Release only in early access. This is a regression, it is not occurring in 4.27.
Result: The editor will crash.
Expected Result: Foliage can be placed without the editor crashing.
