You should be getting the scroll gump at the end of the match which has some information about stats, which is separate from the battle status gump, are you not getting that gump too?Trouble is Kyronix you don't always know the battle is over. The gump doesn't always update correctly.
IMO a period where the town zone is enabled (so you cannot place fields) but the guards are not then 5mins later the guards are added (time for all fields to fall).
Area affects and area spells have always been the same just need to be careful.
