*facepalm*

This could be any one of a thousand problems.  It's nearly impossible to give a meaningful response with what you provided.

1)  Tell us what editor you're using if any
2)  Tell us what you've changed
3)  Give a screenshot*
4)  Tell us what you've done to try and fix this problem
5)  Maybe even tell us how we can reproduce this problem ourselves (give us a step-by-step of what you have to do to get this problem to occur -- that way we can tell you if you missed a step or whatever).



* Take a screenshot with the "Printscreen" key on your keyboard (or Alt+Printscreen to just take a picture of the active window).  Then go in Paint and Edit|Paste.  Save the image and convert it to something internet friendly like PNG or JPG using some kind of image conversion utility (or if you have XP, I think you can save directly to PNG).  Upload this image to a web server or hosting site -- there are several free ones like imageshack.  Then either provide a link to the uploaded image here, or embed the image with the [ img ] tag (the bottom-left BBC tag button -- just above the smilies when you post)

I might be wrong -- but I wasn't aware you could have tiles spaced oddly like that.  I mean -- I thought that you had to have two tiles between places.. notice how the castle is directly above the space below it (and similarly the spade on the right is directly above the space below it -- you'd probably have a similar problem there).

My advice would be to keep everything spaced out.  Move that whole portion of the map from the castle to the space below the spade up one tile.
