The bug
Upon opening a freshly unzipped Skyblock 2.1 world in 18w08b, the MC client hangs at "Loading world".
latest.log
contains lines referencing several "java.lang.IllegalArgumentException: bound must be positive" errors.
Notes
- The world file is initially in old Beta 1.8 format and must undergo conversion.
- This conversion cannot happen in 18w08b; it insists on recreating the world, even if you click "I know what I'm doing" – possible 2nd bug candidate there.
- Conversion of the world performed under release 1.12.2, where it loads just fine.
