Light in the Sky

• Add Online Detector, Cooperative Advancements, Advancement Plaques
• Add some messages on first join/startup
• Add advancement for Cooperative Advancements
• A few adjustments for early-game advancements for smoother start in The End
• Remove a splash message

v1.2.1:

• Re-enable recipe for 'The One Probe Readme'
• Vanilla Skyblock preset now has more descriptive name
• Fix bedrock disappearing outside the Nether
• Twerk advancement now allows sprinting too

This will probably be the last update for 1.16.5. There is some GitHub activity on Draconic Evolution's 1.18.2 branch, so I may end up porting the modpack to that version after all. BetterEnd will likely not survive the update.
