Hi Kacey

The map is looking as beautiful as ever, despite the green line.

I'm assuming you mean the very very pale green haze at the bottom of the image? I've no idea what it might be, but how did you fix it all those other times. Surely it wasn't necessary to replace the background texture several times?

I don't use PS, and I'm only a GIMP novice, but in CC3 I would start by switching off all the sheet effects, which I think would be equivalent to making a copy and deleting all the effects - shadows, bevels etc. That probably is nowhere near as easy in PS as it is in CC3, so I guess the next best thing is hiding the layers one at a time - which I guess you have already tried anyway, which is how you know its something to do with the parchment layer?

What kind of effects do you have on that layer?

(and here I have to apologise for the fact that I'm going out right away after writing this comment so I may be some time in getting back to you, even if you respond in only a few minutes - but maybe it will get the ball rolling for someone else to figure it out )
