the reason is because i first tried Contract("0x.") for the same address and it cached a nothing-ness i can't override

sorry this is false, i actually figure this out.. is a weird bug that happens when you are referencing a contract on a forked network that hasn't been deployed yet, meaning you are setting a block number before a deployment you need, which is think is a fairly common scenario, faintly recall someone mentioning this problem before.

several pot. fixes here, idk.. better error..
