The MultiSellExplorationData event is broken. The array of discovered systems has blank names for all but the last one listed. Also with this new format, there doesn't seem to be any way to know which individual bodies you got discovery credit for, just the total number. I sold all my DW2 data last night, and this is a representative entry:
{ "timestamp":"2019-07-07T03:58:06Z", "event":"MultiSellExplorationData", "Discovered":[ { "SystemName":"", "NumBodies":27 }, { "SystemName":"", "NumBodies":15 }, { "SystemName":"", "NumBodies":2 }, { "SystemName":"", "NumBodies":1 }, { "SystemName":"", "NumBodies":1 }, { "SystemName":"", "NumBodies":2 }, { "SystemName":"", "NumBodies":3 }, { "SystemName":"", "NumBodies":19 }, { "SystemName":"", "NumBodies":4 }, { "SystemName":"", "NumBodies":3 }, { "SystemName":"", "NumBodies":15 }, { "SystemName":"", "NumBodies":1 }, { "SystemName":"", "NumBodies":13 }, { "SystemName":"", "NumBodies":34 }, { "SystemName":"", "NumBodies":25 }, { "SystemName":"", "NumBodies":23 }, { "SystemName":"", "NumBodies":10 }, { "SystemName":"", "NumBodies":2 }, { "SystemName":"", "NumBodies":12 }, { "SystemName":"", "NumBodies":8 }, { "SystemName":"", "NumBodies":27 }, { "SystemName":"", "NumBodies":4 }, { "SystemName":"", "NumBodies":1 }, { "SystemName":"", "NumBodies":23 }, { "SystemName":"", "NumBodies":4 }, { "SystemName":"", "NumBodies":4 }, { "SystemName":"", "NumBodies":13 }, { "SystemName":"", "NumBodies":2 }, { "SystemName":"", "NumBodies":9 }, { "SystemName":"", "NumBodies":11 }, { "SystemName":"", "NumBodies":8 }, { "SystemName":"", "NumBodies":1 }, { "SystemName":"", "NumBodies":12 }, { "SystemName":"", "NumBodies":48 }, { "SystemName":"", "NumBodies":2 }, { "SystemName":"", "NumBodies":9 }, { "SystemName":"", "NumBodies":23 }, { "SystemName":"", "NumBodies":19 }, { "SystemName":"", "NumBodies":1 }, { "SystemName":"", "NumBodies":31 }, { "SystemName":"", "NumBodies":54 }, { "SystemName":"", "NumBodies":11 }, { "SystemName":"", "NumBodies":2 }, { "SystemName":"", "NumBodies":1 }, { "SystemName":"", "NumBodies":1 }, { "SystemName":"", "NumBodies":4 }, { "SystemName":"", "NumBodies":28 }, { "SystemName":"", "NumBodies":21 }, { "SystemName":"", "NumBodies":9 }, { "SystemName":"Eowrairks EB-E d12-0", "NumBodies":12 } ], "BaseValue":29702006, "Bonus":2809455, "TotalEarnings":29260336 }
