Issues I've found
The shipwreck shows up as a red brick.
Consuming "waterskin" gives you -2 thirst and it can be used infinite times.
Boars become invincible after a certain amount of time
the item "mushroomspore" is nowhere to be found, after frantically clicking the ground for 10 minutes
The commands "Grant etc." and "God" do not work.
Now what was that about not releasing a bug-filled version?
Suggestions
More animals, maybe...
Snake: Poisons players, requires them to create a cure out of various berries and/or snake venom (obtained when killing a snake)
Leopard: hunts players, comes out at night
Crab: Kill them for crab meat
Night and day system- yes
Fixing all of the above problems.
When creating a tribe, it makes an invisible boundary. If other players enter this territory, it will tell them a message like "Now in Bobobob Territory"
Having the player's hunger, thirst, and fatigue start out at 0 (It makes more sense, 100 hunger seems like a bad thing)
