When spawning an Actor containing a Destructible Mesh and immediately doing a sphere trace to that actor, upon repeated spawns you will get False results for some time then True results for a while then back and forth.
This is a regression from behavior in 4.7.6 which resulted in consistent True results in the same spawn-trace setup
Also Reproduced in Main Promotable-CL-2589716
Attached are the Sample Project in 4.7.6 (showing working behavior) and 4.9 (showing broken behavior)
For Attached Sample Project
1 - PIE
2 - Press "K" multiple times
RESULTS - Trace Results are inconsistent
EXPECTED - Trace Results should return true
