Needed Codex map with all regions, artefacts. Preferably big enough to be able to zoom and see where exactly regions starts and ends, also that every cell would be equal to coordinate (as example 4000x4000 or even 8000x8000) with grid every 10 or 20 cells or even smaller, to be aware about coordinates. (WHY? Answer to dummies - to strategise basics) Also would be nice to get data in extra format that it would be possible to process it... matrix or smth idk.
The one that has been provided ages ago is either outdated or too small.
Also, announce dates faster, to be able to get players ready.
