Hello, Me and my friend discovered a modpack called "CrackPack".
CrackPack is an updated version of "MindCrack". We tested it out on singleplayer world and it was very fun.
We wanted to play with eachother so i thought "Hey, we can create an aternos server with crackpack on".
But the problem was that Aternos didn't have CrackPack on it.
So i would be very thankful if you added "CrackPack - the updated version of MindCrack" to Aternos. 
Small description: CrackPack is a very fun modpacks with most of the big mods like, Tinker's construct, Applied Energistics 2 and maaaany other mods that makes this modpack so fun to play. If you like to make massive mechanics, this modpack is the best one.
Thanks for attention / StudioMaker
