These past 4-5 days I've been experiencing host migrations, and they are following a consistent pattern.
When trying to play cross-region, i migrate with a 100% consistency, no exceptions. I live in Hong Kong.
My data collected so far:
In-game region set to Asia: migrate at 32 minutes into the mission.
This happened 7-8 times or so in a row, at the exact same timestamp.
When i host myself, they will all "leave squad" and I will still be left alone in the session.
In-game region set to USA: migrate at 43 minutes into the mission.
Twice in a row
Playing a public matchmaking game with randoms, no host migration.
Since then, I have continued HM with a 100% consistency when playing with people from other regions.
When using the network analysis tool, it says "all systems nominal, no uPnP or natPmp detected".
I've tried with and without VPN.
This seems like a really strange phenomenon to me. Can anyone who understands this stuff use this to gain any insight into what it might be ?
