So there I was, making changes to the new templates that the developers provided as defaults for beginners. the columns, walls and roofs materials can be altered during planning but the floor plan designs cannot be changed. it just give me a window reporting an error. I tried to change the floor plan manually but it is not saved in my template and the building refuses to get finished with the missing floor. I hope this report will be answered with a fix for the bug.
I tried to upload the screenshot of the error but your forum won’t let me due to me being a new user so I typed it down down instead.
Message: Uncaught ReferenceError: toolID is not defined
line number: 204
hope this can help.
