I had earned 1,000,000,000 plus credits from other boinc programs from join date April 03, 2016 until I got 4 newer computers and started running Collatz Conjecture only about August 2016. Those credits showed on BOINC Combined Statistics until recently. BOINC Combined Statistics does show join date April 03, 2016., but as mentioned only Collatz Conjecture credits are shown.
Are those earned credits gone?
