If there's more than one actor of the same class, effects don't work.

Are you using the node “get all actors of class” somewhere? If so, check the “get” node so that it isn’t hardcoded to 0. As this means it will get the first actor only as reference

Yes I am, but how am I supposed to hardcode it to more than 0? Theres an option ( An integer wich is equal to 0 ) And if I set it to 1 when theres 2 actors the second one works. If it is 0 the first one works.
