Using /maspawn hobobarrel_static_alwayson chat confirms the entity was spawned but no entity appears. Works fine with the other hobo barrel prefabs, just not this one.

Do you see the debug text that gets drawn at the base of the entity, or is that missing as well? If the text is there, that could mean the entity is invisible. If the text is missing, that means the entity must have been instantly killed for some reason.

No debug text appeared either, it seems like it was either not spawning or just being killed the instant it spawned.

It seems that prefab is not an entity. When I try to spawn it directly via console with spawn hobobarrel_static_alwayson, I get the following error in the server console.

CreateEntity called on a prefab that isn't an entity! assets/bundled/prefabs/static/hobobarrel_static_alwayson.prefab

This means you cannot spawn that prefab via the plugin. I will make an improvement to the plugin to better inform the user about the issue.

Cheers, that explains that, thanks so much

This has been fixed in v0.14.0, so the plugin will no longer allow placing prefabs that can't actually be spawned.
