hi guys, im the server owner, and i want people to not be able to create flint and steels (or just not be able to use them). I have world guard, and essentials spawn,essentials, and world edit (these are the ones that are important) I want fire to be able to spread in pvp but not in survival world and also flint and steels can be created in pvp but not in my survival world how do i do that? and also I want lava buckets to not be able to be placed down, by players nor dispensers, but lava bukkits can be used in a furnace. and fire should not be able to spread becuz of lava. Pls could you guys help me with this, ive added a worldguard flag that fire-spread deny but fire still spreads. And if you guys think of other things that would help then pls tell me (ps is there a way to prevent gravel or sand bombing spawn?
