Map objects disappear

[LeozinH1]

I created a custom map with a map mod editor, I've added some items however, as I move away from the added items, and go back to them, they disappear. Can someone help me?

I think you can avoid it by using ymap dlcpacks instead of json/xml maps

I converted xml to ymap and then rpf but it did not work: s

This seems liking a streaming issue, that's odd.
