Any chance when a player tries to craft a blocked item we can spit a message out to chat for them to read? Would love to be able to tell my players what's blocked automatically. A lot of our blocked items are purchasable with economics and if I could customize said messages we would also be able to tell them how to get their hands on those items too.

Same question

Either that, or anything set to false just be flat out missing from the crafting & also removed from the tech tree completely.

Trying to craft something and nothing happens at all definitely seems a bit lackluster, new to server players will think its a server bug and just leave.

@LaernuTairos I've heard multiple devs say the changing of the tech tree and crafting UI is impossible. Most anyone has been able to do is block the opening of them entirely and make a whole new UI I think. 

It would be really nice of FP to provide hooks to for this sort of thing, I think people could do a lot with a custom server if that was available to developers.
