So there is already the Mineshafts & Monsters modpack on aternos, but it is wayyyy to heavy for server to even run.
As a solution there is a Lightweight version of the modpack(made by the same person) called Mineshafts & Monsters - LITE.
It does meet the requirements and it would be really cool if you could actually run the pack on the server. Instead of it crashing each time you try to start the server.
Theres this thread here: link Where someone requested it and it got accepted, but its not on any of the modpack pages
plzzzzzzzzzzzzzzzzzzzzzzzzz (its really a great pack)
