Mariculture isn't confirmed to be added into the mod pack. So don't expect too much from it. Especially if it gets removed tommorow. Just experimenting.
Now that I was finally able to update my mod pack, I was finally able to do some testing with the mods I have added, It seems, that the quests didn't update in the Hardcore Questing Mod. I will try to find a fix for this.
The Minecraft Comes Alive Mod is officially included into the modpack.
