Falling Blocks bypass Build perms

[lexiccn]

What steps will reproduce the problem?

1. Build a kick-ass sand shooter outside someone's town
2. Fire the kick-ass sand shooter into their town
3. Sand lands in the town as a block

What is the expected output?

I guess that the sand breaks on landing like when it lands on slabs?

I should add this isn't really an issue; I was working on patching for my own use but I didn't find any mention of it so I thought it was worth noting in-case it's not intended

Is there even an event for when sand goes airborn?

[lexiccn]

Not that I can find - my way of patching was (in my mind so maybe doesn't work out this way) to try and block it when the sand block is created; if the origin was a falling block

In saying that; it would break falling sand from people who do have perms so it's 50/50

I can't find anything on Spigot for becoming a falling block however

[lexiccn]

Apparently EntityChangeBlockEvent can record both it changing into & from a falling block

In theory then the location can be checked on both?

If that's teh case then something can be done.
