I'm hoping for some help, an explanation or a resolution because I'm now at my wits' end and frankly considering unsubbing entirely from this game purely because of this.

Ever since Patch 4.25, coincidentally when Eureka Anemos was released, I have had nothing but 90002 errors.

These happen regardless of what I am doing - I can literally be standing and poof. Gone.

It happens a lot more if I zone, but it really isn't predictable. Before that patch it only happened once in a blue moon and generally tended to be 90001 which is my own connection dropping.

This has followed me across computers and OSes as I have built an entirely different computer with entirely different installs of the game and changed OS on a new HDD to boot, and not only that it's occurring on my mother's PS4 copy too, though with more limited amounts.

I've reset my connections, my router numerous times (my PC is hard-connected, not by wi-fi) and nothing is coming up as broken.

I know 90002 is not generally on my end as that would be 90001 and I'm only very rarely experiencing lobby server errors.

Timing-wise they can occur almost constantly, four or five times a night or even three or four times an hour, or they can take an hour or two between instances.

I am in the UK/EU playing on Balmung (NA) generally, but I believe this has happened on both Primal and Chaos Data Centers too.
