What is CoroUtil?
Same as in the All the Mods 10: To the Sky 2.0.4 guide
CoroUtil is included in this pack as version 1.21.0-1.3.9, shipped as the NeoForge file coroutil-neoforge-1.21.0-1.3.9.jar. The pack lists it as first included in this pack version or earlier.[1]
Unverified The sources I have don't describe what CoroUtil does in gameplay, so I won't guess. There is no in-jar guidebook and no platform description to draw on. I also found no quests that involve the mod, and it isn't on the ATM Star quest path. You don't need to unlock or craft anything for it as part of the pack's progression.
Until more is confirmed, treat CoroUtil as a background mod that you'll mostly see in the mod list. If you run into it in a crash log or a version check, the version above is the one this pack ships.[1]
