I have created an Actor subclass, added it to a sub-level, which is then embedded in a Persistent level. When I load up the Persistent level and double-click on the added Actor, my Mac freeze and eventually reboots. Once rebooted, it generates a kernel panic report. I would be happy to include a zipped-up version of my project to an Epic employee for analysis.
Obviously, this shouldn’t be happening. Apple is responsible for some part of this as well, as user-level applications should not be able to trigger a kernel panic in this manner. My engine version is UE4.19.2 and my macOS version is 10.13.6 (17G65)
