Im trying to prevent players from building bases at certain ylevels... I figured your mod would help me accomplish this, but it is not working. When I use the below script, I can't place ANYTHING below Y25, from any mod. When I try to add a global "allow" command before the one below... it ignores the one below. I also tried it with minecraft:furnace, and the results are the same.

{
"maxheight": 25,
"mod": "enderio",
"message": "Pressure at this depth will not allow this block to stick.",
"result": "deny"
},

Can I recommend an example of a Place Event script on your wiki... it seems like every other function has an example, except that.

The problem is that at this moment the 'mod' attribute is not supported for place events. I'll see what I can do

Fixed for next release

This is still broken.
