Please accept my sincerest apology
In recent updates, anytime I adjust the game data for Forest Fellers it will overwrite your previous saved file.
I understand that this could cause some upset depending on how much time you spent there. So, I'm big sorry.
I'll be looking for a way to change that file without overwriting it in the future, but for now, I'll guess I will be manually setting the replay-ability with every update that adjusts that data.
Thanks for playin, love u
