Why aren't my animations loading in a Group Game?

So, I opened up a place on my account, and decided it was time to publish it as a Group Game to allow my brother to easily build maps, and so I could update without having to continuously switch accounts.

However, I noticed that the animations for running and jumping weren't playing. I was using custom animations for running and jumping, but they aren't loading in the Group Game. The same goes for any decals and particle images.

Script for loading animations:

game.Players.PlayerAdded:connect(function(player)
	player.CharacterAdded:connect(function(char)
		if char then
			local hum = char:FindFirstChild("Humanoid")
			local animateScript = char:FindFirstChild("Animate")
			animateScript.walk.WalkAnim.AnimationId = 'http://www.roblox.com/asset/?id=203185287'
			animateScript.jump.JumpAnim.AnimationId = 'http://www.roblox.com/asset/?id=203185316'
			animateScript.fall.FallAnim.AnimationId = 'http://www.roblox.com/asset/?id=206600697'
		end
	end)
end)

Everything works fine in the original copy of the game, but not the one published as a Group Game.
