That is what TL say. It was same with the alpaga : you got one free but once you started, you need more because train deliveries and airplane orders ask always for more.
But the main problem is why we got so many Truffle orders (train/airplane) when we don't have expanded there
We even can't make the Truffles items when we bought the truffles in newspaper.
When alpaga and the tunas/salmons were introduced, we didn't have so many alpaga/tunas/salmons orders !
I could at least fill same train until 5 gems. Now i fill less than 1 train for 10 trains !
"Discard them" you will say ? Then where is the fun in the game ?
I already put a bad rate for the game because the game has gone now completly silly !
