why it was closed :D

It's on pause because we were not able to generate many collectibles, so I had one and it's already gone during first attempt to run test. Need more collectibles (but I cannot generate them as services don't work for me in Russia)
branch - test/test_sending_nft

We can pause that for now (but please keep the branch! ) . It anyway should wait for #445
