I think anyone here would need more details before being able to answer you in a fully informed way. I tried to look for any replay under your name, but nothing was showing up, so I couldn’t really look to see a specific reason.
That being said, I’d suggest looking into destruction credit mechanics and seeing if any of those things might’ve contributed to another player perhaps inflicting more severe damage than you. It’s hard to know for sure.
