Was in middle of raid when game crashed out, probably because of bad wifi. When I logged back in and looked at my watchtower it showed 2 losses to that player.
I know it will automatically lose if I crash during a raid but it seems to have logged that same battle twice, and potentially lost 2x trophies.
This happened about 11:45 PDT today 5/24/2021. You can see in the screenshot there are 3 entries from today, which would be impossible because it shows I’ve only used 2 raid flags. Also the two identical ones happened at the exact same time, which is unlikely to occur with normal raiding.
