**Title:**  
error when editing the building template or when in custom design mode

**Summary:**  
I get an error when editing a building or when creating a building in custom design mode. if i place manual walls or slabs sometimes i receive an error. This also happen when i just click the building again.

**Steps to reproduce:**

1. place a floor next to the building you want to edit
2. normal walls can’t be placed while extending the existing building; i have used manual walls (errors pops-up after placing a few manual walls)
3. error after placing the second wall.

**Expected Results:**  
my expectation was to extend the existing building (dining hall) with a few new walls and a roof. Place a few crates and all the cooking equipment to finalizing the dining hall.

**Actual Results:**

**Building designer error**

**Notes:**  
Additional to this issue, is that adding a roof isn’t possible.  
I use F5 every time to reset the UI.

I couldn’t find a topic that was almost the same or the topic was to old.

Additional question, is it possible to upload logs from the game? I saw that most of the things what the game does and what i do is logged; I have found the stonehearth log which i can upload.

Hey ! Building problems are known and yeah, they are a huge pain in the a…neck. If you don’t want to wait for the next version, stick to the already built templates, it should work.  
Anyway, I don’t remember of a UI error for the buildings, let’s call our super [@moderators](https://discourse.stonehearth.net/groups/moderators) 🕶
