Joiner Xenotype Filter

Joiner Xenotype Filter

This mod lets you block unwanted xenotypes from being generated as joiners, refugees, quest reward pawns, transport pod survivors, hostile pawns, and similar humanlike pawn generation cases. Set your blocked xenotypes in the mod options. When a blocked xenotype is generated, the mod replaces it with an allowed xenotype instead.

Features

• Per-xenotype block list
• Filters wanderers and instant joiners
• Filters quest reward colonists
• Filters transport pod crash survivors
• Filters refugees and quest lodgers
• Filters hostile pawns, including raiders
• Supports HAR-based alien xenotypes
• Stable handling when only Baseliner is allowed
• Designed to avoid long reroll loops and freezes when many xenotypes are blocked

Special Handling

• Sanguophage is treated as an event-only xenotype.
• The filter will not select Sanguophage as a normal replacement xenotype.
• If Sanguophage is blocked, the SanguophageMeetingHost and SanguophageShip events are disabled.
• Includes an option to allow Baseliner shamblers even when Baseliner is blocked.

Important Notes

Blocking every xenotype may leave the filter without a safe replacement and can cause pawn generation issues. It is recommended to keep at least one normal xenotype allowed. HAR alien races vary widely in PawnKinds, race setup, graphics, and mutant compatibility. Some special events may still need race-specific compatibility handling. Shambler events in particular use RimWorld’s mutant system, not just normal xenotype generation, so alien races that do not support shambler mutation may not work correctly as shamblers.

Requirements

• Harmony

Compatibility

This mod is designed to be safe to add to existing saves. It does not mass-edit existing pawns. It only affects newly generated humanlike pawns in the selected contexts. It can be used with HAR race mods and other pawn generation mods, but mods that heavily modify pawn generation or add special PawnKinds may need additional compatibility handling.

Recommended Load Order

Load after Harmony. When using HAR race mods, load those race mods before this mod. This mod was created entirely with the help of AI.
