Wrong Servers After Updates

Hello! Seems like whenever a new update is released, certain gamemodes throw me into the wrong servers. Last season, after the mid season update, I was constantly thrown into games with around 180 ping (only fixed after a few hours). This season, I am being thrown into games that range from 140 in Junkentstein’s Revenge to 300 in the Haunted Masquerade.
PS: Junkentstein’s Revenge also seems to have new bugs introduced. What is going on lately?
