While trying to download the 3.0.3 version of the pack I am running into an issue that states that there is a dependency missing or no longer available. Not sure exactly which mod it is related to but it flags as Addon ID: 244651. I was previously able to play 3.0.2 but that version was downloaded near when it released

Not able to reproduce this one, downloaded with both MultiMC Import & Twitch Launcher. Tried with both 3.0.2 and 3.0.3. Sometimes the launcher will throw these errors for reasons unknown, but if you can use MultiMC and give that go for the modpack download(s).

For that you just need to DL the Zip from CurseForge and then import a URL into the MultiMC Launcher. 🙂
