This is like trying to herd cats. I rebuilt that to use slot 824 but now TS4Ever has released the last two in his series and used 824 and 825 ( apparently he did not read this post.......
)
Battle of Rimini Airfield 9/44 is now in slot 826 in my master game and will be released as 826 whenever we do another mini update ( probably spring 2020 )
so... if you have more planned in that series the next one can use 827 and I PROMISE not to move it again
