Chaaze's Moonfix

The mod replaces the earlier Administrator spawn system with a new one, so players see the Administrator more often. A spawn cycle begins around day 15 as the moon nears its full stage. Every 2 to 3 days a dice roll with a 1 in 10 chance is made, and when it succeeds the Administrator attempts to appear near a random eligible player, at a distance of 75 to 150 blocks.

The spawn timer only advances in the overworld, and only players in the overworld who are in loaded chunks can be chosen. The author notes that the change is intended to reduce the load from frequent requests, and that it significantly improves performance in both multiplayer and singleplayer. The mod applies some changes per request, and states that the spawn logic avoids certain cases, such as a player underground in a cave, a fight with an active boss, or a circle around the player that is mostly water, which would indicate an ocean.

The mod is client and server, so the server and every player need it. It is published for Forge only, with 1.5.6-1.1 as the latest file for 1.20.1, and it is released under the MIT License without being open source. The author states that few internal parts may cause compatibility issues and that these have been safeguarded.
