If possible, please explain to me, a simpleton – did the bug occur on its own, or was it because someone very respected (no irony intended) changed the time?
The HeroesWorld server is in a different time zone. The time was set completely correctly; it just wasn't suitable for us.
By the way, this bug hasn't been fixed, as my messages are still being sent even now. I wrote about it here: /topic/5663/
As I have already found out, the changes I made, which were supposed to move the clock back 12 hours, were not saved after yesterday's technical support activities. Therefore, at the moment, I will change them again; now, apparently, the changes should be saved.
