+	//    2. User B accepts the teleport via lure request
+	//    3. The server sees the init request from User A and the accept request from User B and matches them up

+	//    6. User B's viewer prompts user to increase their maturity level profile value.
+	//    7. User B confirms and accepts increase in maturity level
+	//    8. User B's viewer then attempts to teleport via lure again
+	//    9. This request will time-out on the viewer-side because User A's initial request has been removed from the "queue" in step 4
