That's by default the case.
We allow unlocking more cores, but not disabling cores. So the engine will always calculate the score based on the default amount of available cores, or higher.
We can link the scores to the competition if they were submitted before the end of the competition timeline. This clearly is an issue from our side and the users are not to blame.
Hm.
A while back we loosened up the competition propositions because users wouldn't get notified if there was a competition matching their hardware specs but didn't match the benchmark application. So the pop-up should appear more often now.
Were you previously getting the message that you could submit the HWBOT Prime score to the Team Cup? But it changed now that the OC4DOGE competition is showing up? In that case it might be related to the hardware database.
