The entities stay while replaying and skipping forward, but vanish when skipping backwards with the "loading world" screen.
They also don't show up in the rendered video.

Sounds very much like #674, will double check once that's fixed.

Had some trouble installing that mod, so I wasn't able to double check but it very much looks like the same thing, so I'm gonna close this as a duplicate for now. Can always be re-opened if it turns out that there's more to it.

Duplicate of #674
