Posts from New artifact effects (visual).
I've encountered this issue before, but I wasn't sure if it was caused by a mod or not. I didn't bother to recheck because I had to wait for about an hour and a half in GameRanger to play a single match. I live in Spain and don't have any Russian friends who play Heroes.
The main problem is that I don't even know if it's fixable, I don't have much experience, and without help, I can't fix it.
Theoretically, with which other mods might yours conflict? Something isn't working for me, but it's a great mod, and I really want to try it. Of course, I'll try going through all the mods I have installed in my permanent build.

Theoretically, it will conflict with other mods that use the same files (the game reads and displays data from the most recently modified mod).
Although there can be nuances (for example, if a folder is used in both, but inside that folder, different folders are used, it might not conflict). And I've encountered other cases as well.
In short, testing is usually the only way to find out.
