Ya know who would know for sure, the maker's of the game. Ask them in the Steam forums "What does In Progress mean/do?". Don't have a copy so I have no clue. I find it best to actually learn the game and it's mechanics before activating options in a trainer.
Well there isn't anything labelled progress
and there are just a few things that can progress
like progress on a challenge aka do 100 of x tile (doesn't increase by 20)
quests on tiles like +10 farms (doesn't add 20)
adding 20 more tiles (doesnt add 20 more)
there is nothing else that can really be "progressed"
It increases the "place down xxxx tiles in total" challenges by that much extra each time you put a tile down. Does not help with anything else from what I have seen.
Thank you, at last a decent explanation of what "extra Progress" does. the steam forums were of little use.
