Just a suggestion if there is anyway you can figure out, to let us demolish demoted buildings instead of level by level. I just learned Corporation in Industrial. I have 5 towns, I had all of the stashes at level 9 and the raw storage to level 18 in each town and had to demote in each one. That took a bit of time and filled up the common chat with information. So I quit and reloaded again so the common chat was not so "busy" with useless information. If it is disabled/obsolete why make us destroy it level by level we should just be able to make it disappear with one click.
