Placing QMG can block workyards and puts them to sleep

Since last update, the home landing zones and QMG behaviour seems to have changed. Mostly for the better, but today I noticed this

The farm in the screenshot was working fine, The QMG was moved to a green highlighted position, the farm then automatically shut down - QMG seems to be blocking the entrance/exit point.

It also happened to me right after the maintenance, I tried some of the recommended "tricks" (cache clearing, logging off for 30 minutes), but my coking plant resumed work only after I moved the QM away from it.
