Well now that all systems appear to be working I've had a look around. The good news (I think) is that Cupmanager did import a bunch of match results *before* the crash, and seems to have kept those results. So, for example, while the HT system shows Bonafide-Ratz as a 1-1 draw in the "replay", Cupmanager does correctly reflect my heroic, epic 4-0 defeat of the Ratmen.
However, I have no way of knowing how many of the results Cupmanager imported were "real" and how many were from the replays. Saltopus-Direwolf is the only one I know for sure didn't come through. The most fair result is probably to assign a draw to that match. Keep in mind that Cupmanager *only* allows me to overrule a match in a 0-0 draw or a 3-0 victory for one side.
If other teams notice that a replay has been imported and the two teams notify me of a fair switch to reflect the "real" result, I will do that.
Please go ahead and issue challenges for next week's fixtures if you have not already done so.
