Not entirely sure of the exact issue, but it affected both Boxmas and Magic when switching to their non-Christmas schedules yesterday at 6am. I believe Magic was supposed to revert to its normal graphics, which it has on the idents and lower thirds, but the
DOG and show title remain in the Christmas style.
Boxmas seemed to have a few more issues, originally both channels were graphic-less, then Boxmas managed to get graphics back except for the DOG and show titles. All is okay now though, with the Boxmas DOG and song titles returning this afternoon.
Yesterday the onscreen logo reverted back to The Box, seems to be 'Box Africa' today...
The Box logo you saw was the back-up DOG, they don't have one set up with the Boxmas logo I guess... the same would apply to the Box Africa logo, which they must have accidentally used (I saw the same when the temporary rebrand happened in November and it took a few days to get the Boxmas graphics to appear).
