id fixer
ID Fixer resolves Block and Item ID conflicts for Minecraft 1.7.10 on Forge, checking for overlapping IDs during startup.
What it does
When the game starts, ID Fixer looks for Block and Item IDs that more than one mod is trying to claim, and attempts to resolve those overlaps automatically. Players do not need to edit configuration files by hand, which is the main job of the mod in a legacy modpack.
The mod is meant to run in the background, with the stated goal of no measurable effect on gameplay performance. The server and every player need the mod installed. Files are published for Forge only, and the only supported game version is 1.7.10.
Installation is a single step: drop the file into the mods folder and launch the game, letting the mod handle the conflict check. ID Fixer is released under All rights reserved and is not open source.
Key features

Block and Item ID clashes are detected and resolved without manual edits to configuration files.
Startup conflict scan
Overlapping IDs are identified during the startup phase, before the game reaches the main menu.
Background operation
The checks run in the background so that gameplay is not meant to be slowed by the process.
Conflict identification
The mod lists which IDs overlap, so a player can see where the clashes came from in a large modpack.
Compatibility

Use cases
Large legacy modpacks
Packs built on 1.7.10 often combine many mods that claim the same numeric IDs, which is the situation the mod targets.
Server setup
A server owner can add the mod to the server folder so that ID clashes are resolved before players join.
Who it’s for: Players and server owners running Minecraft 1.7.10 with Forge who combine several mods and want overlapping Block and Item IDs resolved without editing configuration files by hand.
