OwO Lib Mod FAQ
20 questions players actually ask, answered.
What does OwO Lib Mod actually do?
It's a library mod that other mods borrow code from, so it adds no blocks, items, or mobs you can use on its own. If you see it in your mod list, it's there because something else needs it.
Do I need to install owo lib by itself?
No. Installing it alone changes nothing you can see or interact with in-game. It only matters when another mod you're running lists it as a dependency.
How do I know if owo lib is working?
You won't see it do anything directly, so the real test is whether the mods that depend on it load and function. If those mods work without errors, owo lib is doing its job.
Why do so many mods need owo lib?
It bundles shared utilities like config handling, networking, and UI helpers so each mod doesn't have to write them from scratch. That's why several unrelated mods can all point to the same library.
Can I remove owo lib if I don't recognize it?
Only if nothing else depends on it. Removing it while another installed mod needs it will usually cause that mod to crash or fail to load.
Owo lib is crashing my game, what do I do?
The crash is almost always caused by a mod that depends on owo lib, not owo lib itself. Read the crash log for the mod named alongside it and check whether that mod matches your game version.
Does owo lib hurt performance?
On its own it's lightweight and mostly idle until a dependent mod calls into it. Any lag you notice is more likely coming from the mods using it than from the library.
Is owo lib compatible with other library mods?
Yes, library mods generally coexist because they serve different dependent mods. Conflicts usually come from two mods wanting different versions of the same library, not from libraries fighting each other.
Do I need owo lib on both client and server?
If any mod on the server depends on it, the server needs it, and clients connecting usually need it too. Check the dependent mod's requirements rather than assuming.
How do I update owo lib safely?
Update it together with the mods that depend on it, since a newer library can break older dependents. If something breaks after updating, roll the library back to the version those mods were built against.
