Windows [BUG] Squidfest objects remains on beach for co-op players on the 14th Winter

[DespairScent]

Steps to reproduce:

1. Load co-op save on 13th Winter and let the second player join (via LAN or Invite Code)
2. The second player must visit the beach and see the Squidfest objects (booth, sign).
3. Now both players can go to bed and skip the day.
4. It's 14th now, the second player must visit the beach. Can be observed that the objects are still there. If you watch as a host, they won't be there.
