Could someone help me to find out what is the reason? No crates on the map just empty markers.

update to the latest version of guarded crate
It's doesnt matter with guarded crates. All plugins which contain Hackablecrate spawning are doing this error.
I know but crate started to show on map for me after I updated to latest version. The cratemarker[0] error happen randomly across plugin. I've asked around, some people had missing crate on map on different plugin but guarded was showing for them, its vice versa for me.
What I noticed was, the error was introduced after FP's 10 years update.
