🛡️ Important Disclaimer

⚠️ Convenience Features & Usage Risks

This modpack includes client-side convenience mods (e.g., MASA (Tweakeroo), InvMove, and the Boat Item View feature from Tweakeroo) that provide optional quality‑of‑life functions such as:

Free Camera (spectator‑like view)

Movement while GUI is open

Third‑person “stealth” view (Boat Item View)

Please note:
On multiplayer servers, these features may be considered cheating or exploits, and their use could violate server‑specific rules, potentially resulting in kicks, bans, or other penalties.

You can safely remove these specific mods if you wish to ensure compliance — the rest of the modpack will function normally.

📜 Liability Notice:
It is the user’s sole responsibility to review and abide by each server’s rules before using any mod-assisted functionality. Any account or gameplay penalties incurred from the use of these mods are not the responsibility of the modpack author.

Play fairly and know your server’s policies.
