Honestly this is more of a problem with you not managing your server properly then the mod itself... If he made the blocks update and replace themselves more frequently then the mod would cause insane amounts of lag. Also why are nukes and other explosives even craftable or placable in the first place unless your using vanilla server. To be honest I doubt theres anything he can do to fix these problems without making the mod a lag monster with block updates and checks. If your running a bukkit server get a plugin like hawkeye or logblock and start banning the retards that are doing this kind of thing. If they cant respect a protected area as private then they dont need to be playing multiplayer anyways. If you using vanilla, your kinda SOL. This mod ISNT a replacement for something like WorldGuard like you seem to be treating it as. Thunderdark is more then welcome to correct me on this but there no real way to fix this without some massive rewrites and effort thats more easily solved by you managing your server better, no offense. As nice as Thunderdark is with trying to implement all our suggestions your taking a tad too far trying to make it into your custom area protection plugin/mod.
Sorry I was not asking him to make it update faster and he also knows there is a update in the works for forge in fact I think the hooks are in for the future. I was only explaining what is happening and giving him my full honest review of what can and what people do to get around things. I think this is things he enjoys knowing about. And yes his mod is sort of a 2 way used mod. One for Protection from normal griefing and the other is more war combat type server sort of mine no rules nothing really.
