Beam emitter freezes when spawned with blueprint

Im having this weird problem where a beam particle I’m spawning via a blueprint (that is also setting its start and end points in case that’s relevant) is not changing at all over its lifetime. In which I mean it seems like its not taking time into account, as it dosen’t seem to have a lifetime and exists until I stop playing the level or disable the emitter , it will not change colors, it wont change its alpha. Its lifetime is set to 0.5 so its not at 0.0 either so it should be dying. Im also only spawning one via burst per event call. In Addition with further messing around in cascade has shown me that if I have any transition time to the target point at all in the beam data module it won’t show up, which makes me think it isn’t updating past when it is created. Is there something Im doing wrong?

This is how I’ve set up the creation of the beam, and the timer to trigger the creation function

As an update I recreated the material and blueprints in 4.18 and it works perfectly fine, so this is something from 4.20
