Wither & Golem Spawn Fix

The mod replaces the vanilla need for air blocks around a spawn with its own structure-based system. When a golem is summoned, the mod looks for a safe position instead of letting the creature appear inside walls. Because a golem's hitbox can suffocate when the space is cramped, the mod can place the next wall blocks at head height so the creature is not stuck.

Two options are offered for handling the case. The first makes the golem immune to suffocation until it lands on the ground, so the code can wait for a useful moment to act. The second teleports the golem toward the direction with the fewest blocks, preferring corners, and can break blocks where that is needed. A golem will ignore directions that contain only unbreakable blocks. Golem following is included, and each feature can be enabled or disabled in a config file, with both options enabled by default.

Wither & Golem Spawn Fix is server-side only, so only the server needs it and players join without installing anything. It is built for NeoForge, with files for 1.21.1, 1.21.11, 26.1.2, 26.2 and 26.3, and the latest is 1.2 for 26.3. The mod is released under the MIT License and is open source, with public source code and an issue tracker.
