I am experiencing an issue where Player1 is for example on the Yongan map and Player2 is on the Seungryong map. Any shout messages sent by Player1 are not visible in the global chat, and similarly, shout messages sent by Player2 are not visible to Player1. Additionally, it is not possible to use the warp function to teleport to Player1 or Player2, or to send whisper messages if they are not on the same map, such as Yongan + Yayang. The same issue occurs with notice or broadcast messages.
However, this functionality works when, for example, Player1 is on Yongan and Player2 is on Yayang, or Player1 is on Seungryong and Player2 is on Milgyo.
How can this issue be resolved? My server is running on a VMBox using Ulthar SF V2 (TMP4 Base).
