There is just one invocation transaction in this block, so it's not hard to tell which one behaves in a wrong way.

It faulted very early on based on GAS values, something went wrong, maybe there is even no contract deployed in our case.

[roman-khimov]

Yeah, it couldn't make an APPCALL based on the stack values it left behind, though I'm wondering why it only consumed 0.011 GAS, it probably should be 0.013 (3 regular instructions and an APPCALL). @fyrchik?

Invocation that creates deploys this contract: https://neoscan.io/transaction/64b32ee43a644ebfcc81532769b4440a1164941032327814914c25e3b7164ee2
