I Have tried many times and Find a way to Reproduce this bug:

1.Create a new Level.

2.Put Two BSP in the Level.

3.Delete the First One.

4.Re-Order the other BSP to the First.

5.Editor Will Crash as expected.

Test With Unreal Engine 4.14.3

Hey JackTM,

So I did test this crash on my end, but when I went to test in the 4.15 preview 4 the crash does not occur. I was able to get the crash to occur in 4.13.2 and 4.14.3, but not in the 4.15 release.

Since this crash does not reproduce in an upcoming release, there is not much necessity to entering this as a bug report. Would you mind testing your test case to see if the crash is in fact resolved in 4.15?

Let me know if you have further questions.

Cheers,
