A small number of users were affected by a UI bug that underestimated the amount of gas required for a staking transaction. As a result, these transactions failed with Out of Gas and each one cost the sender about $50 in ETH.
Hello, thanks for reporting. However we didn’t find any bug from the UI. Metamask set the gas limit based on the gas estimation and sometimes it’s too low which makes the tx failed. I suggest you can increase the gas limit to avoid this.
