Load / unload Stream level crash
Build Type: Binary Unreal Launcher
Build version: 4.14.3-3249277+++UE4+Release-4.14
Detailed description of the issue: Got stuck in a big project where we used Lighting Scenario's to easily switch styles in an apartment. Everything works like a charm in PIE mode, but unloading/loading these streamed levels crash in standalone or packaged version. Happens 100% of the time.
Decided to test the matter in a new project to limit influencing factors. Started from the first person controller template and made the most simple lighting scenario switch I could imagine. Works in PIE. Crashes in standalone. 100% of the time.
Added testproject as Attachment Link
Basically unloading + loading another streamed sublevel set to lighting Scenario, in one blueprint call, crashes 100% in standalone...
Screenshots/Link to video:
Action 1: Create New project from First Person Blueprint template
Action 2: Create 2 new levels, add a mesh in each in a different position, add them as sub-levels to the default persistent level, set as lighting scenario, and build lighting separately for each scenario.
Action 3: Use Load Stream Level and Unload Stream level in one blueprint event. (level blueprint or any actor or UMG blueprint is fine).
Action4: run in standalone mode, activate above blueprint event-->crash.
