Hey there,
theres a better work around to keep your centers running, even at max capactiy:
1.) Stop sending your trucks to a neighbor city (just to be sure)
2.) Build a new recycling center.
3.) Wait until it starts working, and has a bunch of materials inside (but NOT full)
4.) Cut of the street, and leave it alone
EVERY other Center - even if full - will now work correctly. (but remember, they are only working
between 7 am and 6 pm)
I have workers trapped in there - dunno if it is required.
