When an entity is inside a sub-chunk (which is marked with blue lines when you have F3+G enabled) and it touches tripwire from sub-chunk above, this tripwire won't activate if it is two blocks higher than the border of the sub-chunk (for example a ghast at y=207 (16*13-1) does not trigger tripwire at y=210 (16*13+2)), but triggers tripwire at y=209 and 208.
- Slime and Magma Cube with Size:5 or bigger
Also happens horisontally - in this case only 3 tripwire lines can be activated and it only affects slimes/magma cubes with Size:12 or bigger
1. Create a Superflat world with the preset
2. Create a ghast cage (blocks around a 4x4x4 area to trap a spawned ghast) at ground level.
3. Place a line of tripwire through the top of the inner area.
4. Spawn a ghast inside.
