I'm having a bug where new items I try to place with effects, for example a hologram asset from sci-fi, won't display until I restart the game. I'm also not seeing any effects while playing, like blood effects when shooting, or explosion effects, glass effects breaking. There is also a rendering glitch when viewing an omni-light effect from a certain distance.

For context, I'm doing a part 1 and 2 for my level because I maxed the assets, so for part 2 I just resaved the level under a new name, and deleted most of the assets. My fear is that because this 2nd part is a copy of the first one, my only option is to delete it and start fresh from a new project, so I'm here hoping for an alternative.

Thank you for you time.
