Due to an issue with the masterFarmer contract, users cannot withdraw
34+
their staked assets as they would normally. Because the withdraw
35+
function is trying to call the harvest function, and rewards have ended,
36+
the transactions are failing. We are now using the emergencyWithdraw
37+
function to remedy this situation, which takes a fee of 25%. Upon
38+
withdrawal, this 25% fee will be sent to the treasury multisig.
39+
Guardians will refund users this fee on a frequent basis. If you have
40+
any questions, please reach out on Discord. We are sorry for the
41+
inconvenience.
