Actor's do not appear to be ticking when a level is first loaded when using a Level Streaming Volume. The Tick event will fire on the second and subsequent attempts.
Edit: After further testing, the Actor's Begin Play is not being called the first time the level is loaded either.
Found in 4.15.1. Reproduced in 4.14.3 and 4.16 Main CL# 3354254
Result: The actor's Tick will not be fired until the level is loaded the second time the streaming volume is entered.
Expected: The actor's Tick would fire the first time the level is loaded using the streaming volume.
