i think it has something to do with massive ammounts of players getting their cooking to 99 too. some people buy like 20k+ sharks just for cooking exp and then just compete with autoers/other players ansell them for a small loss.
Naw actuacllay this is good for me so I don't have to go spending 1m for 1k sharks everytime instead buying 1k sharks for 500k-600k it seems better for pkers and people who don't have lot of money but it sucks for the fishers, oh well....
