Modpack: why were mods removed or are missing?

The installer says "client mods removed" or "download mods yourself"? What that means and when you need to act.

After installing a modpack the installer sometimes shows notes about single mods. Here is what they mean.

"Client mods removed"

Many modpacks contain mods that only work in the game on the PC – for example graphics, shaders, minimaps, menus or camera mods. On a server, these mods crash the start.

Our installer detects this on the first start and moves such mods into the mods-client-only folder. You don't need to do anything – your friends have these mods in their modpack on their PC. Which mods were moved is shown in the green message in the Installer tab.

If you do want a mod on the server, move it in the File manager from mods-client-only back to mods and restart. If the server crashes then, it really was meant for the game only.

"Mods missing" – the author doesn't allow downloads through other sites

Some mod authors only allow their mods to be downloaded directly on CurseForge – not automatically through other sites such as our installer. We leave these mods out and show them to you with a link.

  • If the server runs anyway, the missing mods are usually visual or comfort mods. You and your friends can often play regardless.
  • If friends can't join or something is missing in the game: download the mods via the links, put them into the mods folder in the File manager and restart the server.
  • If the server doesn't start without them, the installer tells you clearly – then the mods are needed.

"Fetched (missing from the pack)"

Sometimes a pack lacks a library other mods need. The installer then downloads it automatically. Nothing to do here either.
