Factories,trains just quit delivering goods for no reason

everything was level 5 more or less and suddenly it started to downgrade

my home appliance factory’s are full with stuff to deliver but they just don’t

and this happens quite often and when i rebuild it all it works again mostly but i’m getting tired of doing so! what could be the issue that is causing it just to quit working
