Modpack version
0.5.0 Server

Describe the bug
Molten Invar can be crafted in Tinker's Construct Smeltery - either by alloying or smelting Invar items - but recipe doesn't show up in JEI.

Screenshots

It is indeed server only. Just spun up a server on 0.5.0 and am seeing the same thing...

Trying to reproduce this in Dev and I'm seeing Tinker's Invar without issue. We are hiding EE's molten invar, however, but that's intentional since it's extra.

Server only issue perhaps?

Perhaps. I spun up my 0.5.0 instance and it's fine there too.

Updating the dev server, will check it out there

well, it's not KubeJS scripts at least. Removed everything from Dev and my local instance and I'm still not seeing Tinker's Invar. Only EE's

Looks like this is on Tinker's itself unless we have a config somewhere that's breaking it.
Stripped the server to just tinkers and JEI and still don't see invar.
