BUG IN THE LATEST UEFN UPDATE!! – Props disappear in cinematic sequences

[besthillex]

Summary

In the editor, my spaceship appears with all the moving parts correctly, and the island’s initial spawn is correctly configured. The problem arises when I launch sesión, all those moving parts disappear, and when I finish the game, the spawn is where it shouldn’t be: underwater, next to the other pieces of the spaceship.

I have added the moving parts to the main ship; they aren’t separate, but rather arranged in a hierarchy, with the spaceship being the main one.

Edit 1: I’ve tried reverting to a previous snapshot and it works, nothing disappears. The problem is that when I add or change something I want to update, even if it’s minimal, like moving a rock, the spaceship breaks again and the parts disappear.

I’m in UEFN, using Windows 11. I created this island, and all I did was add some devices with basic code that I added previously, as well as other changes that weren’t related to the spaceship and its parts.
