The Chainlink oracle latestAnswer() function is deprecated. Instead, you're supposed to use latestRoundData().
Using deprecated functions can result in the PriceOracleImplementation not returning the correct value anymore. It will affect the availability of that module.
Usage of latestAnswer(): https://github.com/bunkerfinance/bunker-protocol/blob/main/contracts/PriceOracleImplementation.sol#L29
You can find the deprecation notice in the used contract itself: https://etherscan.io/address/0x986b5E1e1755e3C2440e960477f25201B0a8bbD4#code#L142
none
Use latestRoundData() and verify its return values properly, e.g. that the price was updated recently.
