Connection and access
Diagnose missing worlds, membership, sign-in, unavailable links, and protocol-limited controls.
#The world does not appear
Confirm that you accepted the invite with the account whose email was invited. Membership belongs to the account, not the browser. Ask the GM to check World settings → Members & invites for a pending or revoked link. Links do not create guest seats; sign-in and acceptance are required.
#The world opens but does not join
Wait for its wake and connection state. Reload once if the client remained open across a server restart. If the server is older than the client, protocol-gated controls stay hidden rather than sending messages the server cannot read. A persistent reconnect loop needs the world id, client version, and visible error.
#A Library link says unavailable
The target may be missing or private. Aether deliberately uses one state for both, so a reference cannot reveal the name or existence of a hidden document. Ask its owner or GM to share it rather than trying alternate URLs.
#A control is missing
Check the current role, active panel, selected document, and protocol support. GM-only controls are filtered from player seats. An action requiring a selected page, token, scene, or readable table is absent when that prerequisite is absent. Closing a panel is different: use View to reopen it.
