We are currently designing on about 250 designs witch we have in the same file as different art boards. In the swatches panel we have created two different groups of colours (each group has 8 swatches). We design in each art board (for example Art 1) with one of the group colours (lets name it A). When we finish colouring Art1 we copy the design in the next art board Art2 and now we colour it using the other group (lets name it B). We save the file and the next day when we open it we find that the design in Art 1 and Art2 have the colours mixed!!! We find that some colours of the group A used in Art 1 have been interchanged with colours from the group B and vice versa...!!!
The colours do not interchange in the colour groups between the swatches panel but in the objects of the designs in the art boards... PLEASE help and fix...
