TyrannisUmbra

The mod says it's prohibited on NA and Asia, but from what I could find, there's no mentions of anything the mod does being banned on NA, and the Asia server modlist specifically says mods that provide direction indicators for spotted tanks are allowed (so long as they're actually, yknow, spotted). The only place I can actually see mention of the mod being banned is on modpack lists. Is there something I'm missing here?
