I have deleted a few mods, because they crash the game. You shouldn't really have crashes.
Also, if when you break blocks, they respawn and you can't collect it, save and quit the game and load back up the world. That usually works for me.
Installing a modpack using the Technic Launcher is easy. If you don't already have the launcher downloaded, visit our download page to get the latest version.
Type in the modpack name (Crazy Craft 2.2 (ORIGINAL)) or paste the following url into the search box.
Finally, click Install at the bottom right of the launcher after you select Crazy Craft 2.2 (ORIGINAL) from the list on the left. The launcher will handle everything else!
