Thank you for the reply. I looked through the file but couldnt find the bit that showed credits. Anyway I looked on INARA and it said 5.1 billion (sept 2020) which was probably the last time I played. So either I got it wrong. Or it did say 5.2 (which was an error) and then corrected itself.
You can open the journal in windows notepad for example and try to find (Ctrl + F) "credits" . There should be timestamped entry at every loading of the game. Just check the files from recent sessions and you should find exact numbers.
looks like this:
{ "timestamp":"2024-07-19T06:42:50Z", "event":"LoadGame", "FID":"F3703576", "Commander":"Florenus", "Horizons":true, "Odyssey":true, "Ship":"Python", "ShipID":35, "ShipName":"SLED DOG", "ShipIdent":"ARK-25", "FuelLevel":32.000000, "FuelCapacity":32.000000, "GameMode":"Solo",
"Credits":4183637108, "Loan":0, "language":"English/UK", "gameversion":"4.0.0.1807", "build":"r303387/r0 " }
