So to get right into
Single-player crash bug
One of the most frustrating bugs I’ve experienced in single-player is that my game can randomly shut down without warning. There’s no freezing, no error message the tab just disappears. And no, I’m not opening anything else on my PC while this happens. This makes the game unpredictable, so I’m forced to save constantly sometimes hundreds of times just to feel safe. I believe this started happening after I downloaded RON on my second PC and selected "Local files."

NPC duplication
First, when I select a nation in the single-player menu, one of the NPCs always ends up being the same nation as me. If I try to change that NPC’s nation to something else, mine ends up changing too.
This only happens in single-player, it has never happened in multiplayer. It seems to be related to color selection. If I pick any color other than red, I become linked to the AI that has that color, i dont play for both but end up having the same nation as them

Multiplayer save/load bug
There’s a serious bug in multiplayer that prevents me and my friends from loading saved games when one of us has been dropped. All the players from the saved game are in the lobby, so it’s not a player mismatch issue. The game starts to load—progress bar fills up—and then suddenly stops, only to show another message saying "Leaving to lobby."
It’s incredibly frustrating, especially when someone gets dropped late in the game, just as we’re about to start a massive war. Half a year ago, we were able to reload saved games even if someone had been dropped. Now, we can’t.

As of now, I haven’t found any other major bugs, but I also really dislike the new "Apply Changes" button in multiplayer. It wasn’t there before and feels unnecessary. It’s also buggy at times, though it’s not nearly as bad as the other issues I mentioned.

I’ve been playing this game since I was 7 at my dad’s place. I’m almost 17 now, and it’s heartbreaking to see the game of my childhood being neglected like this. RON is the only RTS where you can actually age up through different eras, and nothing else compares. I believe that creating a Rise of Nations 2 would make a lot of money. Alternatively, the developers could do what C&C Generals did—release the source code to the community so players can fix and improve the game themselves.
Please, anyone and especially the developers if you see this, we and I need help
