Niagara Parameter Collection doesn't work for Simulation Stage

1. Open attached project.
2. It's very simple: Color is set with NPC parameters
   [Image Removed]
3. Only difference is one niagara system has the Color module in Particle Update, and one has it in an otherwise empty Simulation Stages

Expected: Both should work regardless

Reality: Color module in Simulation Stages doesn't work

Note: If set directly as a constant value on the panel both work fine. This only happens if we have NPC parameter as input.
