This issue has been handled perfectly. The list of other players' mods must be displayed and clearly visible. If, once the feature is well-designed and implemented, a player hides their mods, they must be penalized.

Is this how you would fix this? It looks correct in-game. champion_infantry_maceman.xml

In any competitive game where there is a winner and a loser, the fundamental expectation is that the conditions are equal for everyone involved. That’s the very foundation of competition. When two players sit down to a game of chess, neither side is allowed to use any hidden advantages. The same principle applies to online matches. Once the sense of fairness is compromised, the match itself stops meaning much. The surprising part is that we even have to explain something this basic. What I’ve noticed is that the game’s easily moddable structure and the looseness of the rules are being exploited. And in all the years I’ve occasionally played this game, I have never seen anyone join a game and say: “Hey guys, just so you know, I’m using a mod that lets me do certain things faster.” Not once. I’m not saying these players are deliberately hiding it but they certainly don’t mention it unless someone asks. Yes, some of the usual suspects are known to people who spend time on the forum. But not everyone spends time on the forum. Being active on the forum is not one of the fundamental requirements of this game (some players don’t even speak English.) Many people simply log in to play the game through the multiplayer lobby and that’s completely normal. They shouldn’t be expected to browse forums just to find out whether certain players are using advantage providing mods. A player who simply joins the multiplayer lobby expecting a fair match has no way of knowing that a particular opponent is using a mod that provides an advantage. That player can easily walk into a game assuming equal conditions and end up losing under unfair circumstances without even realizing why. Some people also seem to reassure their own conscience by saying things like “it doesn’t actually provide an advantage.” But if you ever run into a match where they’re forced to play without their mod (usually because a host insists on a clean game) you can quickly see how much they struggle without it.  I won’t even get into a debate about why these mods provide an advantage, because that’s exactly the kind of discussion they want. Something that drifts the topic into ambiguity. I guess they expect something like laboratory results, but even if you somehow show them that, their response will just be to question the validity of the lab. I can’t even justify explaining it since anyone with a bit of common sense can see the inequality for themselves.  Creating mods is perfectly fine, no one is against that. But if a mod gives you an advantage, then you should be playing against others under the same conditions and you should honestly disclose your mods to every new player you encounter (although, I’m afraid these mods could spread like a plague, as new players may be tempted to use them to succeed quickly.) To be honest, I wasn’t even aware that things like this were happening in this game. Realizing that some players I thought were simply very skilled, were actually cheaters, was disappointing. I hope this issue will be addressed and that the community as a whole realizes how much these practices undermine the quality, integrity and spirit of the game. 

The bug tracker has patches marked as backports. However we can only make a release that's compatible with R28. That means no simulation changes. Only translations and bugfixes not touching the simulation

what are these signs? xD
