Horizontal stone beams missing

[dim spear]

I purchased and used the beams recipe from the tortuga people, but the horizontal stone beams are not there. I have the horizontal mahogany beams though so that means the recipe was used already.

Thanks for the report, we'll check it.

I could be wrong but there is horizontal beam for those arches and it is in arches section. Perhaps that is the intended one but in weong section

That should be the solution.
