Aave Seatbelt report

https://github.com/bgd-labs/seatbelt-for-ghosts/blob/main/reports/Aave/0xEC568fffba86c094cf06b22134B23074DFE2252c/134.md

There seems to be some infrastructure problem on Tenderly, which causes the state transitions to show erroneously (aTokenAddress instead of the correct interestRateStrategyAddress). We have double checked both payload code and events emitted, and everything seems correct
