Do bug reports go here? Any way. If you die to self sacrifice in blood magic, you do not leave a grave currently and all your stuff just dissapears. RIP full draconic set and sword, and all tinker's tools :'(
Bloodmagic doing all kind of weird things when you die due to self-sacrifice isn't really a new 1.10 issue, I remember that it used to crash your client on Hypo. (Or still does, cant check right now) and I just had a quick look at BM's github to look for that issue. Found similar ones, not that one, but only had a quick look. Anyway, thank you @Zhainius for bringing that to our attention, I will tag our @Administrator team, so that someone can have a look at it. I am very sorry about the loss of your items. Unfortunately we have a strict No-Refund Policy, so that there is no way we can give them back. You can read up on that here: click me Have a nice day
This is an issue with the Gravestones mod, currently any death short of vanilla causes will not cause a gravestone to spawn. I've contacted the developer in regards to this issue, currently it is not supported in a multiplayer environment other than a forge, so it will not form graves for modified deaths at this time on Direwolf.
