So there is nothing in received although there should be something, otherwise how could it send anything?

[fyrchik]

There are received transfers on neoscan: https://neoscan.io/address/AKinx3r8YPQRxS6WyLEGEQvcNNAEkto3Ek
However the same token was received on another asset: tx 08ceeba9dca38946e5656e9143087d77a369829f1f58511525e7a167bdc1b325 invokes 1e892bd588ea4ab409b3a93d3049d6115c6727f3, but next transfers of NNN token use 53b7577befb37d4d3b95a02f60f5da8933ab5f04. So this can be related to contract migration.

Funny enough, neo-tracker.io continues to show transfers for the old contract. E.g. this tx 0884e123ba07c368448b6e48498221e80dd589602ac4b0991a439f5761d187eb, even though it is in FAULT state on both C# and Go nodes.

Even though we have transfer log for migrated contract, we invoke it's decimals method to find the correct way of displaying values.
