this is not happending in the begin version of the game with workshop mods
after the 1.3 update the DD2 update something and if your character die, the game will freeze with the custom corpse post
now in 1.4 if you die , you will become tombstone as usually, but if you go out the menu and return to the battle, the custom corpse will show up again and everything will stay normal with the custom corpse lol
I dont know why it happend in this way, I test and study a bit, this is the only way I can avoid the game bug but still have it showing.
