If something happened to the front-end or any other issue arise (such a DDOS attack), in order to withdraw your funds you should:
1) Find the pool ID of the pool you have staked.
Go to 9.poolInfo and type 0 to 6 (the actual list is at the bottom)
2) Click onto the LP Address
3) Click onto the Pancake LP button
4) Double check the LP is it the one you are looking for
4) Do an emergency withdrawal (Connect to Web3)
