Socketed, BP, Particle ribbons show up in editor but not in game!

Whenever ribbon particles are socketed inside a blueprint, it randomly either shows up or disappears in game mode, sometimes if i have 6 ribbons socketed only 1 shows up, other times none of them work. But they all do seem to work fine in the editor. What gives?

Lately a simple GPU particle system that i have placed in the scene doesn’t play in the game either but many other articles i have in the scene seem to play fine.

Is this a memory issue somehow (I doubt since i have a good rig) or a bug somewhere?
