Я нашел место в котором падает: ``` WITH ? as ForkBlockNum, ? as ForkAddress, ? as ForkTypes, ForkedLastStates as ( SELECT BlockNumber, Time, BlockHash, TxHash, Address, Contract, DataJson, Project, Key, Type, Ver as LastVer, Sign FROM state_log FINAL WHERE BlockNumber >= ForkBlockNum AND Address = ForkAddress AND Type IN ForkTypes ORDER BY LastVer DESC LIMIT 1 BY Key ) SELECT BlockNumber, Time, BlockHash, TxHash, Address, Contract, DataJson, Project, Key, Type FROM state_log WHERE BlockNumber < ForkBlockNum AND Address = ForkAddress AND Type IN ForkTypes AND Key IN (SELECT Key FROM ForkedLastStates) AND -- ПАДАЕТ ТУТ Ver > 0 ORDER BY Ver DESC LIMIT 1 BY Key ```
