Thanks for the tips peewee; I tried shortening the lines and making sure that dialogue = tags were at the beginning of each line. I checked for unnecessary spaces at the beginning, in between lines, and at the end and I found none. The font modifiers were all codes I saw used in other quest files, mainly ^003 ^007 and ^009 and all 4 characters were on the same line. The map numbers correspond correctly where applicable.
It is odd, the quest was working before I went in and modified the quest file.
I am going line by line and it accepts my first line of dialogue. As soon as I add a second line, whether it is separated by a \r or not, tagged by dialogue = or with it just being a part of my first line it crashes. The crash doesn't seem to be dependent on how the line is formatted but merely by the presence of a second line of dialogue, which makes no sense to me.
