hello!
error occoured

모드 불러오기 실패: Error in assignID: entity with name 'aai-lane-fast-loader-stacking' does not exist.
Source: aai-lane-loader-s-loader (loader-1x1).

ALL ISSUES are being fixed in a unified loader mod, since in 2.0.65 Wube added a new loader property (respect insertion limit) and trying to manage 3 possibly interconnected mods is not worth the trouble. I will send a message here and update these mods accordingly once that combined loader mod is released.

I also encountered this problem.
It's likely caused by launching the mod alongside the mod AAI Loaders - Stacking and Filtering
As I understand it, the name is being truncated incorrectly, which wasn't originally intended for these loaders.
Here's a temporary patched version that should work, and it also fixes the launch issue with the mod Miniloader (Redux)

Boss! We're waiting for the combined version! :))))

This has been marked incompatible for loader utils since it fills the same function

Boss, you're right, you marked mini-loaders as an incompatible mod, but I think you can avoid that and give users the option to install both mods if they want, especially since fixing the incompatibility is literally just one line of code :)
Please don't deprive users of the ability to play with both mods :)

I won't be adding support for miniloaders. If that developer wants to update their mod to get it to work however they decide to do that it's fine. There's enough jank going around that trying to account for it on this end is not going to fix it.

This mod has been depreciated, please use Loader Utils
