I decided to post this as a possible bug after starting this topic
http://www.adventuregamestudio.co.uk/yabb/index.php?topic=34204.0
The topic should read
-10 line(possible bug), could someone please change that for me?
Thanks for the report. It says line -10 in this situation because it doesn't know which line number to point you to in this situation, since the } is missing and therefore not on any line. I'll have a think about whether this could be rephrased in future.
