We recently had our server crash, we thought the issue was that the file size was too large as the hosting service was unable to backup the world file so we used Amulet to remove unwanted chunks. I was able to confirm the trim was successful in game but the file size hasn't changed. It's currently at 4.3GB, same as before I completed the trim.

Is there something else that would be contributing to our file size besides the chunks? We are a larger server, we've been running on this world for almost a year now with at least 20 active players, we had issues when we first started the server with the file growing drastically but with regular trims, it stopped jumping so dramatically. Is the world just bugged?
