Unreal Engine Crashes when deleting procedurealfoliagevolume

So for some reason when ever i try to delete the ProceduralFoliageVolume, unreal engine crashes.
Here’s the crash log and .dmg file:

Hi

It happens (crash like this) not only with foliage but also after changing for example actor/object type as reference or type in code/blueprint. If your foliage is procedural, this is connected with code somewhere. I think this is bug - if you can change actor or object type - engine should not crash but it does. It should just block change possibility if reference is bad.

It can happens for example if you change object/actor ref for Cast to … with parameters set or get from this casting - if new object not have correct parameters. Or if in next code you have reference to variable that no more exist - in short words, if referenced object is not compatible more. It happens to me few times, now I just check my code better.

Well the volume isnt connected anywhere. This is how it started not to work, I simulated procedural foliage and it took some time and did generate foliage but when I clicked on play it crashed so on the next startup I decided to delete the procedural foliage volume and which ends up causing it to crash. I didnt clearly understand what you meant but I have the volume nowhere connected other than on the landscape.
