 ### Fixed
 
+- Issue where the unified bootstrap created a second world that ran a duplicate of every default system next to the default world. (#4243)
 - Ensured a useful and human readable error is logged when a NetworkVariable is trying to serialize a private or protected type. (#4239)
 - Issue where `NetworkAnimator` logged an error for a trigger-conditioned transition into an Exit node, and a client that joined during that transition, or during one into a sub-state machine, did not synchronize with it. Transitions that pass through Exit, Entry or sub-state machine nodes now resolve to the state they reach, and a late-joining client cross-fades from the matching originating state when several states transition into the same destination. (#4238)
 - Ensured all callbacks are wrapped with exception handling to avoid silent errors. (#4161)
