Thanks for the replySideloader modpack contains all of the necessary mods for the game to run as it should be.
It contains mods like clothing, maps and stuffs.
You can play without updating it.
In fact, I never update mine but I do keep my eyes on mod update in the discord server.
But some mods that uploaded to BR repository doesnt always come from discord server, usually things like character clothing.
So it might be good to do an update from the updater once in awhile.
Also, if you are only playing the main game, I dont think you have to check the update frequently since as I mentioned above, usually its just new set of clothing etc.
But its different for Studio one.
Studio modpack contains props, maps and stuff for you to use in the Studio so I would not recommend to download that if you dont play it at all.
I hardly ever play studio, just the main game, and I download cards every now and then
I am running the update again, without the Items for Studio
it's now over 80GB and still slow AF, so hopefully there will be a fix for the slow updates
I get pretty pedantic about staying up to date, but if it takes this long, it just gets stressful
