But as soon as I build new residential, they get "no job" icon then get deserted

Greetings everyone, I had a huge city on one region and a dirty/manufactoring region next to it. After obliterating my city to start anew, the Residential demand is extremely high but Industrial demand is negative - all the way down. Nearby dity/manufactoring region factories are still on full capacity but trying to build more does nothing. Although houses have the 'no job' icon, no commercial or industrial zones are developing. Any suggestions? What could be the problem? Edit: the only mods I use are to lower Crime, Hi Tech job fix and Carpool fix
