About this Modpack
This modpack focusses on tech, exploration and quality of life mods to enjoy in a social setting with friends and family.
The pack started in 1.19.2 and almost all features carried over into 1.20.1.
Warnings when upgrading your 1.19.2 world to 1.20.1:
- Bookshelves will loose their inventory. First go move out all items from your bookshelves if you're not ok with loosing it.
- Scout pouches and their contents will be lost, so first remove their contents before updating to the 1.20.1 version.
- Campanion items will be lost (the mod is not for Minecraft 1.20.1 yet.). Grappling hooks, sleeping bags and rope bridges, etc., all now have replacement mods for similar functionality.
- Defensive Measures mod not 1.20.1 compatible yet, so you'll loose those traps, turrets and cannons.
- Many mob mods (e.g: Goodall, Mega Parrots, etc.) were not 1.20.1 compatible yet, so those mobs will be gone.
- ItemSwapper removed - not so ideal with modded, so I stopped using it.
- Your keybindings will be reset to modpack defaults for 1.20.1 (which differs from the 1.19.2 version)
- Some Prefab materials might be missing, so some prefab structures might have their walls gone, for example.
(My main focus is the Colonies and Technologies pack, but I'll try keep this one up to date for 1.20.1.)

Getting Started:

- Hold the vein mining key for vein mining. (default ^ or ~)
- Hold the Crawl key to crawl whenever you want. (default caps lock)
- Origin ability buttons (Where relevant, default g & h.)
- Combat Roll (Default Mouse 4)
- Multiplayer Ping (Default Mouse 5)
- Go deploy your first Prefab starter base (It has basic stone tools, leather armor and food in a chest somewhere)
- Explore a bit for loot
- Build an Alloy Forge for smelting ores
- Use Compact Storage, Extended Drawers and Tom's Simple Storage for easier storage management
- Build a steam powered drill for 3x3 silk touch branch mining
- Build a Weapon Crafter for some guns
- Eventually, go to space with your rockets :)
Some Default Keybindings:


Focussing on Modrinth mods only (hence the name), where possible. (Had to use Compact Storage from Curseforge for the 1.20.1 version, due to the Modrinth version not being up to date.)
Also intentionally avoiding magic mods, to keep the pack more family friendly, where feasible.
Known issues and workarounds:
* If picking up a map from a chest causes a client crash: Delete the map from user inventory via NBTExplorer.
