feedback1 integrate: 隐德来希's candles standing at the time limit are no leaks (an honest client result was rejected)

A co-op 联防 battle that timed out during 隐德来希 S3 listed the 心烛 (in no spawn
schedule) as a leak, so the server rejected the client's result ('leak key').
Pre-existing on master; the merged bots reached it on fullmatch seed 116.
