I can't build more Sunken Stove?

[suri80s]

I have now 5 of them, when I try to build one more, it shows this up...

9591

Then I try to click some other oven or stoves that need to be build, I find that some of them can be build as they always do, but some of them can't...that's very weird to me, can anyone help? Has anyone experienced the same situation?

Click away from the little hammer icon; it acts as a tutorial button letting you know it has to be built. Clicking away from the hammer should let you then place and purchase the appliance.
