All I did was sort out the tiles TLP, number them and started editing them one-by-one in TLP.
When I finish a letter, I load it up into Rew and see how it looks. The a was perfectly fine with it's coloring when I completed it, so then I moved onto the p. I did the p and wasn't happy with it totally, so I worked the bottom half over again. When I was alright with how it looked, I loaded it into Rew and then basically from A until the 60, there's that discoloration and I'm clueless as to why/how.
If you are willing to take a look to help me fix this, I would be grateful. Haven't touched anything else because it's just...annoying me knowing it's not right.
