I presume this error was so persistent during testing that the game specifically checks that produced thing is within boundaries of correct things: units, buildings, SS parts and wonders. So even if this glitch is reported in replay, at least these abominations do not actually spawn into a game. In most cases it would be just " ", you are lucky that you jumps into some string. Sometimes because of this glitch AI builds legit things that it should not build, including Wonders of the world. I have no idea what data is written here and why this field exactly is usually corrupted. Maybe all other fields are corrupted just as frequently, but it's not that noticeable.
