lan-bootstrapper.gd and noray-bootstrapper.gd both had a host_only()
function that referenced BrawlerSpawner (class_name from forest-brawl).
Since examples/forest-brawl/ is excluded from exports, the type was
undefined, causing the entire script to fail loading with:
'Could not find type BrawlerSpawner in current scope'
This meant the Join and Host button signal handlers never existed,
so clicking them did nothing — no error shown, no connection, no UI change.
Fix: remove the unused host_only() function from both bootstrapper files.
The dedicated server was spawning a host avatar (peer 1) via
player-spawner._handle_host() and _handle_new_peer(1) on startup,
which registered RollbackSynchronizer subjects with the netfox
rollback system. Since no client input exists for peer 1, the
rollback system tried to record state for freed/recycled objects,
flooding the log with property-pool.gd errors.
Fix:
- Add spawn_host_avatar @export flag to player-spawner.gd
- Set it false in headless_server.gd before starting the ENet server
- PlayerSpawner._handle_host() skips avatar spawn when flag is false
- PlayerSpawner._handle_new_peer(1) skips avatar spawn when flag is false
Server startup is now clean: no property-pool errors, no RPC path errors.
