A number of our UEFN Fortnite Islands had Niagara Effects that we made and were working fine. With this last update, they stopped working. They look fine in the Niagara Editor in UEFN when looking at them. They even look okay in the UEFN Editor and we can manipulate them for changing colors, etc. But, when we launch them in Fortnite they are no longer working. They did work before the update. Anybody else see this? Any suggestions so that we can have our effects that we spent countless hours working on and got them looking good in Fortnite to work again. We compiled them all again, double checked materials, etc. But, no luck. It kind of wrecks our games.
