British Loyd carrier bit file

[SIPRES]

Hello,

I was playing an old scenario (Ortona), then I have seen that the *.bit file is not good for the British Loyd carrier.
After checking with Unit viewer (very good tool), I ve seen that LOYD carrier Graphic had been changed and would fit the bit file I currently see when selecting unit.
So why do I get the old graphic still displayed on game? due to old scenario design?
