The most logic workaround would be if players would think on how the suggestion will affect old saves that has a possibility of breaking it and finding a easy but simple way around it before suggestion any kind of crap*
In all terms of seriousness, people should just think if their suggestion will break old saves instead of having something like this. 6_9
I really support this.
I mean, just like potbelly said, we have so many saves and so many elements that one day any change will just break saves.
