Hello, I had the exact same thing happen to me. I asked in Chat and Alexanightfire asked me to add my story to this.
I was on [US] RustEZ Scourge PvE | Zombie Alexa said the logs state I was killed by a wolf around 11pm.
I used /home to teleport to my home and I logged out to join the non-zombie RustEZ server and create my first base. I assume log in times can be audited and compared to the time of death on the Zombie server. Hopefully, anyway.
I lost about 790 diesel fuel and an M249. The rest is arbitrary.
I was second guessing myself but then my son stated that I teleported home and logged right out to join the other server, so it was witnessed.... for what it's worth. 😃
It appears my death marker is my base per the below screen shot.
I was at the Giant Excavator before teleporting back.
Thanks!
