ok... please tell me in detail what happened... like; what time you send your attack... what time it hit... (please show me the report) what time your soldiers got home... things like that... I don't know if I can do something... but it's kinda weird it happens to you twice... I never heard it happens to a player twice...
Just forget these 10 catapults. I usually delete "Arrived Army" reports instantly so I don't have the report anymore. By the way I don't send all my catapults normally so it's kind of hard to trace what has happened. But I will keep all reports from now on just in case all my trebuchets are missing when I wake up one day in future
but no offence.
It's just annoyed that my army are gone not by honorable war but just system errors.
