Game closes instantly after installing a guard mod
Likely cause: Version mismatch between the mod and 2.0.2.
What to do: Check the mod page for a 2.0 build. Remove the mod folder and relaunch to confirm the base game is fine.
Modding
Frickbear's 3 has an active mod scene, mostly custom guards and custom night presets. Almost every broken install comes from stacking two mods before testing either.
Verified against v2.0.2
Install mods into a clean 2.0.2 install, one at a time, and back up your save folder first. Most mods are published on GameBanana under the game's mod hub. If the game stops launching, remove the most recent mod before doing anything else.
This site does not host mod files. We describe the process and link to the platforms where creators publish their own work.
Adds a playable night guard with its own dialogue and office sprite. Risk: Low. Installing any character mod also unlocks Fritz early, though Lunatic stays locked until you clear Hard or finish as Vanessa.
Adds challenge presets to the Custom Night roster, sometimes with new modifiers. Risk: Low. The safest category to try first: it does not touch the story campaign.
A pre-completed save, typically 100% or a specific ending state. Risk: Medium. Always back up your own save first. A save file replaces progress rather than merging with it.
Replaces sprites, voices or music cues. Risk: Low to medium. Audio replacements can break the cue-reading skill the whole game depends on.
Save data for GameMaker Studio titles usually sits under %LOCALAPPDATA%, in a folder named after the game rather than inside the install directory. Copy that folder to a dated backup before every mod change.
Likely cause: Version mismatch between the mod and 2.0.2.
What to do: Check the mod page for a 2.0 build. Remove the mod folder and relaunch to confirm the base game is fine.
Likely cause: A save-file mod replaced the save rather than adding to it.
What to do: Restore the backup you made. Save mods are swaps, not merges.
Likely cause: An audio pack replaced cue sounds.
What to do: Remove the audio pack. Several animatronics are only counterable by sound.
Likely cause: Both modify the same script or roster file.
What to do: Keep the one you actually use. Load order does not fix two mods editing the same file.
