So, the current iteration of tests/integration/test_calculation.py is actually mining a ton of blocks (2.3m), this could be what causes it to fail. I actually need to update it to no longer be mining all those blocks due to a change we made to use timestamps instead.

Are you able to pin-point which test call is failing? Usually this error occurs when you accidentally pass in an ethereum address where a number is expected.

Not really, no but I will check if this is the case. I doubt it, because usually eth-abi Python library is very good about detecting mismatching w/ call types, but you never know.
