Hello. I opened minetest today, after about a month of no activity, opened my world, and when I got near certain region, it crashed....
I have minetest 0.4.14-dev
Ubuntu 14.04
this is the debug:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all: 2016-10-03 18:26:21: ACTION[Server]: singleplayer [127.0.0.1] joins game. 2016-10-03 18:26:21: ACTION[Server]: singleplayer joins game.

The code in question is:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all: local rad = minetest.registered_nodes[node.name].groups.leafdecay -- Assume ignore is a trunk, to make this -- work at the border of a loaded area if minetest.find_node_near(pos, rad, {"ignore", "group:tree"}) then return end

It's part of the general leaf decay function. It should probably read more like this, to avoid assuming its arguments are going to be there:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all: local rad = minetest.registered_nodes[node.name].groups.leafdecay if not (pos and rad) then return end -- Assume ignore is a trunk, to make this -- work at the border of a loaded area if minetest.find_node_near(pos, rad, {"ignore", "group:tree"}) then return end

Make that change to minetest_game/mods/default/functions.lua, and you shouldn't get any more crashes. However, there's still a node somewhere that doesn't have leafdecay set correctly. Finding that is probably more trouble than it's worth. If you see any odd leaves in your game, just remove them.

Thank you duane. My game doesn't have "minetest_game/mods/default/functions.lua", or at least, the "functions.lua" files that i found don't have the code you mention. Anyway, since you pointed me towards leafdecay, I deactivated moretrees mod and the game does not crash any more. Thanks.

Any idea on how to fix bad argument #2 to 'find_node_near'
