I have the same problem, but instead of spamming my console with NotifyArrangedAddress or such, it just functions normally for a few minutes, then says "POSTING TO MASTER SERVER FAILED! RETRYING IN 5 SECONDS..."
"*** ENDING MISSION"
It's certainly not my internet and this hasn't happened before V20.
Also, I have quite literally the maximum amount of Datablocks allowed, so I'm not sure I can disable add-ons one by one without getting carpal tunnel.
