The mod will chrash when loading a save where the mod has not been used and give this error.

"
The mod Comfortable Loader (1.1.0) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event comfortable-loader::on_configuration_changed
LuaTechnology doesn't contain key effects.

The mod does load when generating a new save and will work after that.

fixed

mmm nope

updated

So does this add the loaders AND beltboxes, because the image you are using is from the Beltbox mod.

only add the loaders
