Problem with laying foundations

Hello,

I can’t finish the foundation with Ardashir.

Previously, the floor was laid using this insulated timber. That went without a hitch. I laid the timber on a sandstone foundation. I always do it this way to save on materials.

But I don’t understand why I can’t finish the new foundation.

It works with Stormglass. I’ve no idea why Ardashir isn’t accepted as a foundation?

You should send a photo from the gap and not so far from it . Maybe it’s too high to attach, maybe there’s a stone preventing it , maybe the server reacts funny right now and after refresh it will allow you , there are many maybes.

I don’t say that we don’t face building bugs , yet this is a case that may hide something else too .
