Lots of key files found, many of them in places I had archived for safe keeping but had since forgotten about. Main problem now is working with the Conquests editor. There is a limit of 999 shields for unit costs, and unfortunately a number of units in Test of Time cost much more, some over 4000 shields (aircraft carriers etc). Does anyone have suggestions or know of a workaround for this problem? Update - Using a new editor that doesn't place such limits. Just a matter of importing some files to it. Just note to anyone interested, I am not aiming to add more units etc to the game. What I will focus on is ensuring balance is maintained with existing units (cost, movement etc).
