Shortly after 3 hours of I started playing this world at 1.11.0.5, the game started using an excessive amount of memory (spikes of13000MB), with extreme amounts of lag (15000 ms).

I have already seen the error reported by the user Joel Abhishek, but unfortunately I read that he does not have a copy of his world before this affected version. Fortunately, I made a backup of the world from 1.11.0.3, which I will attach here. The only problem is the size of the files, 90 and 60 mb respectively, because of this I will share the link to a folder on Google Drive.
