If McMillan discovers siberite detection in am09, (at least if he is in the lab as a scientist) he will explain the new technology to himself.
I think this happens in all languages, I've played it both Spanish and English.
PD: I also wanted to report a small typo in the first mission (am01) in Spanish: In the medal screen, the medal for "Cyrus Parker saved" in Spanish says "Cyrus '''Parkera''' a salvo" but it should be "Cyrus '''Parker''' a salvo". It's so small that I wouldn't call it a bug.
Window that i choose to leave or to stay in game, while quitting has no background. Its see-through.
I have found white dot at minimap. There was Oil marked.
Currently, campaign loading screens are displayed very shortly, since we all have fast modern processors. You can't read map briefing then.
Once map loads, loading screen shouldn't dissappear until key is pressed or mouse clicked.
"Press any key to start" text could be displayed on the botom, where map stuff texts are showed.
Make the OpenGL Texture used for storing the main games image (Map, Units, etc) only update when something has actually changed. Also only update the area which has changed and not the whole of the texture.
Multiplayer chat could be divided into 2 groups: chat, which would be visible to everyone in the game (accessible via ENTER key), and chat, which would see only allied members in your team (accessible via <SOME_OTHER> key). You wouldn't have to mess up with radiobuttons all the time when you want to say something to other players then.
