Unexpected disconnect/crash

Hello,

Throughout the last few weeks I have had multiple unexpected game crashes.
The only error that is given is an unexpected disconnect however my internet connection is fine and uninterrupted.

What is interesting is when I am able to log back in (takes around 2 minutes for the game to actually reconnect when logging in (internet is fully working in parallel so it is not an issue on my side) my instance has disappeared and my inventory has 'rolled back'.

All crashes have happened whilst mapping only. Never had any crashes with the campaign, temple or any other content in the game except end game mapping.

Running unique abyss tablet - unforeseen consequences, abyss tablet, delirium tablet. Nothing juiced, just alch and go.

This is annoying as I have lost close to 50d in loot due to the roll-backs and unknown potential loot from lost content.

It is happening on every map. I am logged into the London server.
Have to admit, in all the years I have been playing POE 1 and 2, it is always this server which has issues. End up swapping to an EU server now and then to avoid this.
