I have no idea what that is but, I'm 100% sure it's for lag prevention with no way to get it higher.
well storage systems are **** and people with op islands with hoppers already placed don't have to worry but like, you could make it the higher your rank the more hoppers you can have
Donor - 50 Hoppers
VIP - 75 Hoppers
VIP+ - 85 Hoppers
Skyfox - 115 Hoppers
Shadowfox - 150 Hoppers
Mysticfox - 250 Hoppers (perhaps Unlimited)
Foxking/Foxqueen - 500 Hoppers (probably Unlimited)
And make a option to increase the hopper count by paying a certain amount
Extra 50 Hoppers - $10 USD $5 USD maybe
Unlimited Hoppers - $50 USD (Just a Idea)
This could be put in the game, considering the hopper limit of 30 is very low and you can't do much with 30 hoppers, becuz on my island there is about 750 Hoppers for my storage System all placed before this dumb update (plus I'm Foxking)
