[1.0.1054] Can't build tailoring benches (not a tribal start)

[dshards]

No mods.

Previously built a hand tailoring bench, wanted to add an electric tailoring bench. Neither tailoring bench is listed under "Production". If I select the existing tailoring bench, I am not given the option to build a copy.

Several options, such as "pants" are missing from the Bills menu in the existing bench.

Screenshots attached, showing both the existing bench and the available buildings menu.

Edit: Checked the research tree, and "Complex Clothing" has become un-researched.
