Did not get 260 banners for clearing a zone in GAC

EA_Gunner, while this is an edge case it is definitely a bug. The game should not say "defeat" but then show the zone as cleared - defeat means you did not beat all of the units thus the zone cannot be cleared. If a character remains after 5 mins that is a draw and you should have the ability to come back and battle remaining characters to claim whatever banners are remaining. There is no in-game text stating that defeating the final enemy characters in that little window after the 5 mins causes you to forfeit all points, including those for conquering the zone. If this is really working as intended the points awarded info section should be updated to indicate that it is possible to earn 0 points from conquering a zone; however this effectively leaves a player in a guaranteed loss position.

The bug here is that the player is able to affect the game state after a loss has been declared. If the game declares a defeat, then all enemies remaining at that point need to stay as they are until the next battle with them. A player should not be able to defeat enemies after they've been told they lost. Either any action taken/resolved after the 5 minute mark in the battle should do nothing, or if the animations carry over the game should wait for the animation and calculations to complete before declaring the end of battle result. Otherwise the player can end up in a contradicting state, as seen here. While OP was ruled to have lost they still defeated all enemy units - this should not be possible.
