Problems with the new Jungle Gallery

I’m fairly new to making maps with UEFN, so if there’s a fix for this please let me know. But whenever I use both the bouncy mushrooms, and a specific tree. UEFN encounters problems that result in these assets that Creative 1.0 can use with seemingly no problem, but when used in UEFN prevent the launching of sessions. I’m making a map that requires these specific trees.

Here’s a screenshot of the log.

@TGF_214 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

I wouldn’t mind to, but the problem only occurs with UEFN. It works fine in Creative.
