The patch is being put on the server.
It can take up to 2 hours.
The server will be turned off by then.
There will be changes in objects, quests, stores.
To connect use the client which you can download there:

Items are complete. Tasks are fixed. NPC shops will be added in the night (probably) and all quests will be adapted soon.

Dear players.
We're working on a more accurate loot of monsters and we are improving quests.
We've already completed helmets, armors and shoes.
We haven't finished improving pants (we're working on it).
Some items may gain new properties and others may lose them, including attack, block and protection.
However, we are confident that you will like the changes and it will improve the quality of the game.
The probable date of the patch is 25/10/2018.

The server was crashing because of the new party system,
server went offline because we found the bug causing the server to crash and we immediately started working on fixing it.
It turned out to be more complicated than we thought but we got it fixed and we will try our best to make the server stable without such unexpected interruptions in the future.
Thank you for your understanding.
