What you were expecting to happen, and what actually happened:
When retreat from a battle in guild war, or program close / crash during such battle, the game treat it as a loss, correctly. No score gained, not be able to advance to next site, etc.
However, that loss is not logged into rooster page. Therefore number of battles done that day reports fewer, as if the player didn’t do their best in the day. That creates headache for guild management.
Steps to make it happen again
Retreat in a guild war battle.
How often does this happen? When did it begin happening?
Since gw of current form introduced.
If you are retreating, you will lose the battle. That’s intended.
If the game crashes for any reason, currently it will also register as a loss. This happens in some game modes with limited attempts as it prevents some players from intentionally retreating the battle, to try and play it again, when they would have otherwise lost.
I’ve already reached out to the dev team to see what can be done in specific instances of crashing, to not consume the GW sigil for that battle, but I do not have any updates.
Currently, all I can assist with is helping out with the cause of the crash itself, if you did experience one?
OP pointed out that the loss doesn’t show in the win or loss ratio. Makes it looks like to others that they didn’t try when the player did try to do the battle and device crashed or player retreated.
Crashes should count as losses since a force close world be hard to differentiate between across all the platforms that GoW exists on.
