Fixes a bug where travelling through a portal while wearing an elytra leaves you stuck in gliding mode until you either mount a boat, minecart, or saddled animal. Its been difficult to pin down which server-side performance mods contribute to this issue. If you are experiencing this bug, flightSync is a quick fix to ensure you dont have to relog or mount a boat, minecart, animal, etc to fix your client.

Bug typically happens while in glide mode while pearling through a portal.

Features

- Portal flight fix — automatically stops elytra gliding when the client receives a dimension change/respawn packet - Lightweight — a single mixin, no commands, no config, no server required - Client-side only — works on any server
