Blacksmith workstation assignments sometimes don't register

I’m on an official server and have noticed an issue with blacksmith crafting stations.

I have each type of blacksmiths and multiple blacksmith benches. Sometimes when I assign a blacksmith to a bench, the assignment doesn’t register and the profession perk doesn’t appear on that bench. Reassigning the thrall usually fixes it.

Other crafting stations (armorer, alchemist, carpenter, etc.) don’t seem to have this problem, it’s only happening with blacksmith benches.

Has anyone else experienced this, or is this a known bug?

Yes.

I removed the crafter i dont want and place them at another location so the T4 i do want is the only one there.

Then i relog. Once confirmed as the main crafter , i bring the other back.

My work around.
