When trying to teleport an area effect cloud, the entity itself is moving, but the particles stay at the position it was before. I tried already applying velocity or teleporting the entity but both methods have the same impact on the cloud. My code is the following:

The output that is produced can be seen in the log, the cloud stays at the same position showed in the picture below. However, the entity gets teleported which can be seen clearly in the log.

Hope you can fix that.
