Both the community and ANet are aware that the new 'Elonian' dye does not stack up with the older ones (Tyrian + Cantha) ANet promised to fix this issue (through Gail) in a future update (or has this already beendone?).
But, I also noticed the same problem with Imperial Commendations. I couldn't stack the 'newly acquired' Imperial commendations on the older heap. Anyone else experiencing this?
I searched through the forum before posting this thread, but couldn't find anything related to this issue. If I was mistaken, do ignore tihs thread

Dyes have now been fixed(at least for me), but now things like scrolls of insight (the scrolls that give you more X.P.) don't stack either.
