Steel Helmet becoming iron??

[Alphacore]

My Steel Helmet that I had not worked on for about 2 ingame weeks, due to not having enough steel, has become an Iron Helmet after I finally finished it. 

Is this a bug and has anybody else had this happen to them?

I can't say that I've ever seen it happen, nor should it be happening in the vanilla game. If you're using mods though, make sure you disable them and test on a vanilla world to see if things work as expected. If things work correctly, then you know it's a mod issue, but if not then it's time for a bug report.

In the event it is a mod issue, and you don't see any likely culprits in your modlist, the easiest way to figure out which is the culprit is to re-enable your mods one by one and test them as you do so. Tedious, but the problem mod will be very obvious once your test results go awry.

To add to what @LadyWYT said, and mentioning even though it should be obvious - but obvious things aren't always - for testing switch between Creative and Survival to get the ingredients you need for testing easier.
