It's the horn constructor, I think. I don't remember when was the last time I used this.

how do you get the horns? the spawn command isnt working and i cant figure out which work station to use lol

Well it's my own server lol

I never played in a server and I don't know how the game handles it, so I don't know what the appropriate fix would be. I only played on P2P multiplayer so far.

Another strange workaround I found is that you can craft the horns at a Saturnian loom on server without crashing the game.

Good to see this back.
I am getting this error on my server tho.
[23:19:06] [Error] Could not instantiate item '[hornbound14, 1, {}]'. (ItemException) No such item 'hornbound14'
it's for all the horns, that's just an example.
Workaround is to just use it in solo play and then load back onto server after you've made the horn you like. otherwise placing the station crashes the game.
