I'm having a very odd problem in my city. I created a mod pack including this one, optimised outside connections, and adjustable consumption mod. I build a city from 0 to 70k people without any problems. Suddenly I noticed "not enough buyers" warnings on many of my industrial buildings, quickly it spread so that 100% of my industries showed this problem. No trucks were in the city, the ports were empty, the train stopped. In desperation I tried clearing all traffic using traffic president, and nearly instantly all my industries started to pop back to life as they spawned trucks to export and move their goods around. This lasted for quite a while, but slowly the problem started to come back. I've been playing around disabling any mods I have related to industries and trucking/cargo but not really seeing any different results. I was wondering if you'd have any insight in this? Perhaps trucks are being forbidden from spawning some how when, over time, they randomly "roll" a forbidden large truck?
