I was making a rough map for surveying and editing later(my phone gps is bad so I need some features to map addresses accurately), but I won't be surveying here for a while so I've remapped the mistakes I've noticed. Mapping terraced or semidetached houses separately is optional as far as I know, and I would prefer to make finer edits after surveying addresses instead of relying on guesswork and satellite imagery.
But I agree and I will be slower and more careful from now on.
