Please don't forget that the game is in early access. It's not a finished product so things don't always work perfectly.

I've run into this problem and can usually work around it since I understand that it's an issue. I think most players who are used to the building system can work around it, even if it can be finicky. Holding left shift to disable the snap to function helps in some cases.

It's very likely they'll fix this in the upcoming "Hearth and Home" update since it's building focused.
