@WolverinDEV, i have to confirm, the server crashes every night at the same time (somewhere at 4: 15 UTC+3: 00), it feels like the server crashes on schedule. Perhaps this is a request from outside...
Unfortunately, I can't provide the server logs yet.
Well I don't think that this is a direct request to crash the server itself.
In hindsight I actually managed to reproduce the crash once (locally) but did not investigate since I thought it has been caused by something I did worked on. At that time I was experimenting with the new token system which resulted in permissions updates.
I've no clue if the update itself has some kind of bug or anything related to that.
Trying to reproduce did not yet succeeded.
