As a ghost its possible to be killed by a cactus thus turning into a SUPER GHOST. also bumping into the block left behind by a player death with erebus as a ghost crashes the game. Have a crash report
crash-2018-08-15_16.23.28-client.txt

And this crash report really makes me want to blame it on a coremod. The stackstrace doesn't match anything I have.

Probobly some weird physics thing then. I didint know erebus had its own gravestone thing. sorry for the trouble Jus tryna be helpful with any mods I use

No problem. Please report back if you find the culprit, maybe I could work with that.

Not sure if its a priority or if its just another thing only for me . but dying as a possessed mob with a gravestone mod active will spawn a gravestone but without your items in it. instead all over the floor.

Also drowning as a ghost. p.s. undead can drown?

I don't take damage from cacti as a ghost, in fact you should phase right through them.

I don't appear to drown either. I think you have another mod interfering.

Weird :o just tested again. am able to phase through cacti but get hurt along the way. alright I don't know what mod would cause it but thanks anyhow

Ok I found 2 issues so far.

1 Voidcraft disables the ghost transperency effect when active.

2 a mod called Vanillafix caused ghost to be able to die to cacti and being underwater. its a good mod tho helpful for finding out the roots of a crash and improving game performance

I wasent able to test the Erebus bone blocks very well as I couldent make them spawn when I wanted for some reason.
