Custom smithy not usable(Solved)

[Druidefuzii]

Hey, i made a race with a lot of weapons and tools.

I made three different "forges" to make the items, since a normal smithy wouldn't fit the "biological theme"
I can select them and choose a bill, but a colonist wont craft there and if i select one and click at the bench, nothing happens
I did copy the smithy, changed the comps ,textures , defnames and costs.
When i change the recipe user of my weapons to the normal smithy, everything works fine.
Even just a 1:1 copy of the smithy with a different defname isnt used and usable by my colonists at all, weird.
Research bench , temperature buildings and my turrets work fine, its just the benches.

Could someone push me in the right direction how to solve this?

Are you seeing your recipes show up in the bills?

I believe you might be missing the Work giver for your custom bench
Check the WorkGiverDefs in Core

@LWM : I couldnt have tried it in my forge if i wouldn't see the bills

@Shinzy : Thanks! The smithys are listed in FixedBillgivers  there.  I know now what to do. I really thought it would be enough to have the class
