Calling UBehaviorTreeComponent::StopTree from a BT node can result in a crash

This is in general not encouraged, but should not crash.

The reason it's crashing is that in UBehaviorTreeComponent::Tick we process node ticks first and then try to access InstanceStack[ActiveInstanceIdx], but if any of node-related code results in calling StopTree the InstanceStack gets cleared and accessing the array simply crashes.
