Basically, it fixes the bug with troops becoming invulnerable after splitting them. It includes the 1.04 fixes as well, so you can apply it directly to a fresh install of the game (any language, including eastern versions). It is not officially supported, but Iām very confident that it works.
My big thanks to all the people who helped with this, and those who had the patience to wait this long. Better late than never I guess! š
