When using a particle system in a blueprint and then moving the particle system off screen and then back on there is the node "Is Active" that can check to see if the Particle is still active. When the particle become inactive the bool does not change.
I've attached a simple test project that reproduces this.
1. Open project
2. Create simple particle ribbon
3. Move the particle system in a BP offscreen so that it can become inactive. (default inactive value is 1 second)
4. Do a Is Active check to see if the particle system is still active once it deactivates
If using attached Sample Project:
1. Open Project
2. Open NewMap.umap
3. Press Play
Results: The node for "Is Active" will return true even though the particle system is now inactive.
Expected: The "Is Active" check should update accordingly if the particle system is active or inactive.
