Here is the compressed world in .tar.xz and .zip format, size is 1.5GB: https://www.dropbox.com/sh/kkmy8iccxyhzd54/AAAELd6Eps6YViP2vQ8gopr0a?dl=0
The context is: I had a small iron farm made pre-1.14. As the mechanic of iron golems spawning has changed in 1.14, the farm become useless. After playing for a few days I have dismantled the farm, freeing the villagers and they started wandering. Then the crashing started.
Every time the crash happens different Entity ID is involved. If you find that useful I can provide all crash reports.
It seems to be fixed on 1.15.2.
