You can ‘t. Don’t want to be crass, but you can ‘t unmerge a tribe. That’s the simple truth of it. Everything would have to be unclaimed and given to the other tribe.
Tribe Names: You shall not change your tribe name more than once within a 30day period, if you require the name to be changed you are required to get approval from the admin, due to raiders changing their names while raiding to hide who was causing it, any unauthorised changes will result in a permaban!
You can make storage boxes to keep your items in. If you’re only playing solo, your items will be safe. In PvP, people can break your storage boxes and steal your stuff.
Nothing changes except that it no longer belongs to a tribe.
Alliances add players and creatures to the whitelist for AI, as if they were in the same tribe. Allied dinos cannot hurt each other with their attacks, so you can fight together without killing each other. Auto turrets will not shoot them.
To do this, the Owner or Admins of a tribe must form an alliance by entering a name and clicking the “Form new alliance ” button in the Tribe Manager, then if they formed or are an admin of an alliance, they must go up to another Tribe’s Owner or Admins.
To create a Tribe, open your inventory and click ” Tribe Management”. Here you will be able to create, manage, or leave your Tribe. To invite someone to your Tribe, approach them and hold the action key (default E) to bring up the interaction wheel.
Survivor default items are not kept, they are left in the death bag (to avoid cluttering your inventory with duplicates of them). Fully stackable, no load order requirements.
One way survivors have been able to nab new dinosaurs in ARK: Survival Evolved is by claiming abandoned tames when their ownership timer expires. Now when players leave servers their tamed dinosaurs will all just despawn/die when the timer runs out.
Wild dinos do despawn if they are lured away from their spawn area and then left alone for some time unrendered.
If you get to the area and there are more unclaimed dinos than you can handle you should be able to admin kill them using AdminCheat GCM this will give you creative mode and allow you to use the rifle to destroy them all.
