DHMPEMFixer Mod FAQ
10 questions players actually ask, answered.
Do I need this mod if I only play singleplayer?
Yes. DHMPEMFixer prevents the client crash that happens when Distant Horizons and MPEM conflict, which affects singleplayer worlds just as much as multiplayer ones.
Why does Distant Horizons still crash after I installed DHMPEMFixer?
Make sure DHMPEMFixer is in your mods folder alongside both Distant Horizons and MPEM, then restart the launcher completely. If the crash persists, check your crash log for errors unrelated to proxy fields—those indicate a different problem.
Do I need to add DHMPEMFixer to my server files?
Yes. Add it to your dedicated server's mods folder to prevent server-side crashes from empty packet sender fields in the Forge server proxy.
Can I use this mod without MPEM installed?
DHMPEMFixer is specifically designed to fix conflicts between Distant Horizons and MPEM, so it won't do anything useful if you don't have both mods.
Does DHMPEMFixer slow down my game?
No. The mod works entirely in the background by injecting mixin code into proxy classes and requires no configuration or runtime overhead.
What's a null pointer error and why does this mod fix it?
A null pointer error happens when the game tries to use data that doesn't exist. MPEM removes proxy fields that Distant Horizons needs, and DHMPEMFixer injects mixin code to keep those fields active so both mods work together.
Do I need to configure anything after installing DHMPEMFixer?
No. The mod has no config files or settings—just drop it in your mods folder and it works automatically.
Will DHMPEMFixer work with other performance mods besides MPEM?
DHMPEMFixer is built specifically to patch the conflict between Distant Horizons and MPEM. It won't fix crashes caused by other mods.
Can I use DHMPEMFixer on Fabric or does it only work on Forge?
DHMPEMFixer is designed for Forge setups only, since the proxy conflict it fixes is specific to how Forge handles client and server proxies.
If I remove DHMPEMFixer, will my world break?
No, your world data is safe. However, Distant Horizons will crash on startup if both MPEM and Distant Horizons are still installed without the fixer.
