Constant Server/Instance Crashes

Currently playing in Pherecia, i encounter a lot of issues with the instances i open in the endgame.

Its hard to replice due to being a serverissue that seems to occure from time to time but about 2-3 times per hour.

I cannot pin it to any of the things i do or the mechanics i play because i have not changed a thing compared to a week ago.

Happens when playing the Map-Endgame
(different maps on different tiers, with or without scarabs, idols seem to not have different behaviour in it)

Sometimes when trying to join the map for the first time sometimes after a while i get disconnected and the map portals vanish. The error that disconnects me states, that the instance cannot be found and i have to log in again. Often the login is taking a longer time than usual.

Happens on London, Frankfurt and Milan Gateways. the F1/Network seems nondescriptive and normal before those disconnects but is hard to track done becuase they appear randomly.

Happens for 5 days now and makes the Endgame really annoying to play because i lose about 20% of my maps/instances.

EDIT: most of the time it includes a rollback of the looted items but not the used map/additional items in the map device slots.
2 times it rolled the inventory "only" some minutes back as i was disconnected in a map and still was left with ~10 collected items

Problem still present and occuring.

Problem seems to be fixed for now
