where are the logs for giving rp each kill and when u won the event? i cant find it

If you have "DoLogging": "true", in the RustRewards config, it'll make a log file in the oxide\logs folder for RP given.

I'm unaware of anywhere where event winners are logged. 

yes i have its to true but the events are not listed in this

Yea, I said that...

Mark as suggestion. It's long needed.
