Async Logger Mod reworks how the game handles background text files to give you smoother gameplay. Normal Minecraft writes down every background event on the main processing path. This causes the game to slow down when a lot of things happen at once. This mod changes that system to work separately without holding up your game. It helps a lot when you play with many other additions that send constant background updates.

Features:
- Background Processing: Moves all text writing tasks off the main path to stop slow downs.
- Heavy Load Handling: Keeps the game running fast even when thousands of messages appear at the same time.
- Automatic Setup: Loads the needed extra files on its own so you do not have to do extra work.
- Text Redirection: Catches basic system messages and sends them to the proper background files.
