Unreal Engine Issues and Bug Tracker (UE-35928)

Description

If FActorSpawnParameters::bRemoteOwned is set to true, calling SpawnActor with this spawn param on begin play has different behavior than calling the SpawnActor elsewhere during runtime.

If using network play (multiple players set / dedicated server set), a crash occurs.

Steps to Reproduce

Create UE4 C++ First Person template Project
Open .sln in Visual Studio
In the Character.cpp file add the following
- in Character::OnFire()
```
	FActorSpawnParameters NewParams = FActorSpawnParameters();
	NewParams.bRemoteOwned = true;
```
- Add "NewParams" after SpawnRotation in the SpawnActor calls
- Add call to OnFire in Character::BeginPlay().
Compile
In the editor Pres the Play button followed by left mouse button (2-3 times)

Result:
Projectile is spawned on Begin Play and travels expected projectile movement path. Projectiles spawned on left click hang in the air and don't follow projectile movement

Expected:
Spawned actors behavior is consistent regardless of when the spawn call is occurring.

Callstack

**Crash when set to dedicated server**
