So why did it started happening only recently? Also could skill launchers cause rev hammers to dissapear after colliding with them?
It started happening only recently due to some code changes to physics and navmesh. Before, when the skill launcher collided with the anomaly, a code bug coupled with a navmesh crack caused the ejection to fail. Now that that bug was fixed, the ejection succeeded.
Projectiles shouldn’t be able to collide with skill launchers, even before this change, because of the unattackable and non-targetable flags. Additionally, the collision radius is like 9 inches and they are on the ground so the projectiles would just pass over them anyways.
