I do not think this problem was related to a lightning strike. First, the only lightning storm that has ever occurred around my home, happened before I set up that map. Second, the nearest map to any wall is 7 blocks from the outside air where lightning could have struck. 8 if you count the map itself. Does lightning AOE extend that far?
Here's the report from a forced crash.
No explosions or any mobs at all nearby. If it happens again, I'll force a crash, if that will help.
I'm not sure what this means. A search for cactus green issues didn't come up with anything but people confused they couldn't craft it. And I'm not playing version 1.12, but a snapshot of the version 1.13, and it won't take snapshots as valid, what was I supposed to do? So, is this a bug and will it be fixed?
