I have been having an issue with launching a session in UEFN. It keeps on saying there is a cook error. One of my blueprints also says there isn’t a static mesh component even though there is one attached to it, bit I may have had that issue before. I have changed basically nothing and I still get this cook error and I am 90% sure I had the error with the Boss blueprint before the 25.20 update but that blueprint error has never been an issue even before 25.20. What I am referring to is this cook error which makes the session not launch.
@ItzGopex Thank you for your report! We would like to look into this further, would you be able to submit a bug report using the form available here? Fortnite Creative
Yes and after doing testing I removed the blueprint that caused the error and the session launched perfectly fine even though I could launch the session with the blueprint in my game before 25.20. I will send a bug report on this.
I got the issue fixed. For some reason the 25.20 update broke my blueprints and I had to remake them.
