Forge version: 1.12.2-forge-14.23.5.2854
Twilight Forest version: 1.12.2-3.10.1013
Link to crash log: not a crash

Steps to reproduce:

1. Starting up the server
2. A player joined and went to the twilight dimension
3. That said player disconnected
4. and reconnected

What I expected to happen:

1. Starting up the server with minimal ram usage (4gb/16gb)
2. After 1 player joining the server and go to the twilight dimension, the server ram usage went up to (6gb/16gb)
3. After that said player disconnected, the server ram usage would go back to its minimal usage.

What happened instead:

1. Starting up the server with minimal ram usage (4gb/16gb)
2. After 1 player joining the server and go to the twilight dimension, the server ram usage went up to (6gb/16gb)
3. After that said player disconnected from the server and server log said unloading dimension 7, the ram usage didn't go down
4. The same player reconnected and spawned in dimension 7 (twilight forest) the server ram usage went up by 2gb of ram.
5. Even when no one is in my server, the server ram usage still around (8gb-11gb/16gb)
