MCCS - new Multiplayer content

The frequent release of updates is truly pleasing! It gives hope that in the future, bugs will be fixed and all artifacts will finally work.

Examples:

Crown of Primordial Energy - when you put it on, the stats don't change; when you take it off, the stats increase, but if you put another artifact on the head slot, the crown's buff disappears;

Sphere of Water Elements + Pendant of Frozen Embrace - both artifacts are equipped, but there is no aura, and when the number of creatures in the enemy stack drops below 15%, nothing happens;

Armor Tempered in Tenebrous - the artifact is equipped, it says it is active for 6 levels, but in battle, no damage is healed. There were no battles with the armor equipped before this. Could it be that it initially has 0 active levels?

Pendant of United Destinies - after a while, the 2nd rank stops working, regardless of how close or far the heroes are from each other, but there is no message about increasing or decreasing stats, and the stats themselves also do not change. Also, when the connection is broken, it is not possible to establish a new one, because the artifact constantly changes from gray to colored, and notifications appear on the map about receiving a gray or colored pendant (as a result, you have only one connection for the entire map. I haven't tried killing or dismissing the connected hero).

No other mods are installed. I created the maps using the built-in map generator in Heroes, and each map was processed through a map processor. The only possible problem that might be on my side (at least I don't see any other), is that I didn't install Heroes. The Heroes 5 files were on a flash drive, which I copied from my old PC when I moved to a new one. Could this affect the fact that some artifacts don't work or work, but with glitches (like the Crown of Primordial Energy and the Pendant of United Destinies)?
