Hi, I've been trying to get my modpack approved but it seems like it's taken quite a long time. I uploaded it on the 17th of August and haven't gotten any indicator saying its been approved or if something's wrong with it.
During the week, rarely more than half an hour. Weekends take significantly longer (better part of a day in some instances) since someone has to look over the project and they are minimally staffed at those times.
In the Select Mods to Install window that appears, select only the box next to Minecraft USING A MOD ON A SERVER When you first play Minecraft, I recommend a modpack instance that isn't Vanilla Minecraft from the Packs tab instead.
Most of the time are just each mod gets loaded one after another, and this happens for 3 loading stages for each mods + assets load time. And since every mod has alot of items & block it needs alot of stuff to load from the json.
