The altar of inspiration from Vampirism when filled with blood seems empty for some reason. This issue only happens when rubidium and vampirism are enabled, and i have no other mods aside from both of them. In the picture i had jade, so we could see that the altar indeed had blood inside of it, but it wasn't being rendered.
