Are you hosting or is your friend hosting? Your friend may be missing wiremod, or its out of date, or could have other mods interfering with it.

Friend hosting, they downloaded the gmodism collection

Friend hosting, they downloaded the gmodism collection

Could I have a link to the Gmodism collection, its unofficial and not supported by me directly. I have my own server collection that contains a mix of required addons, addons useful for building, and maps used commonly on my servers that is linked on the workshop page of the mod.

Sure, https://psteamcommunity.yuanyoumao.com/workshop/filedetails/?id=552512871

I'm seeing pretty much all of the required addons there.

When you say the hud disappears does this mean it doesn't work at all in multiplayer or that it goes away after some time or event? Does the EGP entity still remain in the mech? Is your friend having any Lua errors being printed into console relating to wiremod or daktek? What happens if you host the server and your friend joins instead?

Well, when i spawn dupe of mech, hud doesn't appear at all, while in single player it works, and no errors were printed (i think) about egp didn't check too

also hosting didn't too

So you're saying that you can start up in singleplayer and everything is fine, but if you host your own server it doesn't work? That's very odd since they should both work the same.
