Whilst i was in the editor making a map for release (You'll see what i'm planning on release ;) ) i went to write the conversations, I edited the "MISSION_END" convo and close the box, after some time a had to re-open the box and it showed "MISSION_END selected, but was showing my "MISSION_START" convo. (Minor I know but still :) )
I have attached a screenshot showing this (Hard to tell so I added another showing "MISSION_START" selected and one with "MISSION_END" showing)
ScS1 = Bug ScS2 = Actual "MISSION_START" text ScS3 = Actual "MISSION_END" text
