[Stan]

The crash occurs in the component manager. The entity that is not deleted is consistently 536870912 The only reference to this is in test_ComponentManager.h

How to reproduce?

The entity that is not deleted is consistently 536870912

On which map?

[wraitii]

This feels like a duplicate of #4616, l186 is the ENSURE(m_DestructionQueue.empty()); bit and 536870912 is definitely a local entity.

[Stan]

It was on every map.

Basically, I would:

1. Open Atlas
2. Launch the Actor Viewer on the Entity Tab
3. Start the game in the main tab by clicking play

The code of the Actor Viewer was changed since then and it creates a simulation context differently so I guess it was fixed by: r21167 Thanks Refs: #5111

Wraitii is maybe right and this was just another way to reproduce it.

One would need to revert back to whatever decision we were on 12 Months ago.
