To add onto this, I just did admin abuse about 1.5 hours ago and got a spike of 10k platform crashes, and my ccu during AA was less than half of what it normally is. (no players actually mentioning crashing though so idk)
I have not modified matchmaking (it has always been heavily weighted to prioritise server occupancy).
My game relies on having busy servers rather than players being split between empty servers, so this is a problem for me. At the moment it has low CCU so it relies on only 1-2 servers being used (which was the behaviour before) rather than players being split up
