52:09       [All]    This game was hosted by lagabuse bot, visit www.lagabuse.com for the rules, ban/unban requests and more.

According to the log, it seems like some lag issue happened and your team left before the tree actually destroyed (from the bot's vision, because of the lag) Afaik it happened before sometimes, it's a rare bug. Admins can restore your psr and remove the bans, wait for their response.

I checked it since -Ragnar- asked for unban, and yeah, as Lagi said its a rare bug, I already unbanned players, some of the admins will restore PSR you lost and give you PSR from victory soon.

[Akuma]

I've just been told that your got PSR you deserved by administrator

if u want to make sure it won't happen again, always wait for bot message:
