Forge/Custom Games Bug : Broken FX Emitters

Dear 343i,

So, when forge FIRST launched, I made a map with this big ol’ gimicky scripted feature in the middle of the map,
and the “Full Effect” relied heavily on the use of FX Emitters, specifically “Steam_Constant”.

It works in Forge.
Looks brilliant.
Open it in Customs and…
…nothin’.

This has been broken since launch.
We’ve had (I think) three Updates since it launched,and I was really hoping this last update would be the one to fix it.

So…can you please fix it?

Love, HOBO ITCHY
