i was working on an mob farm and server restarted when i joins their was an delay like always and then i got insta killed by an zomb went back and no grave spawned
From player to player: Look in the surrounding. The grave is trying to find a empty spot where to fit in. Sometimes it can be away a few blocks i think. I am not quite sure how the grave decides where to go or why it could dissappear but have you searched the surrounding?
There -is- a rare bug, maybe only native to DW20, where a grave wont spawn. It has happened a few times during these last weeks now, and has been mentioned in the forums. Like SilentStar says, look thouroughly through the area where you died. I've seen graves spawning more than 10 blocks away. If, it is the case you cannot find your grave, then ask a moderator who's available to lookup your death. If they aren't good and/or familiar with the prism parameters yet, tell them to send either me or Silent a msg in the forums. I'd help you out, but my PC is broken atm -.-' If it is the rare case that no grave spawned, then I can only sadly remind you of the no-refunds policy.
.-. ask anyone on TDT if i have enough of each enchant on an item from my mobfarm, save silktouch, i have over like 100 last stand 2 golden chestplates, that was obtained within a few weeks .-. just ask
