The guns and grenades work but when I try to hit a cannon with a torch I get this in the console.

Any ideas why??
thanks

I have the same error. What do you mean by moving aside the file?

There should be a file names cannons.ser in the plugins/Armageddon folder. Just delete it.

its ok I have fixed the cannons...
There is a problem with a conflict with the WAR plugin...
WAR does not recognise the explosions and spams the console so I can now only use the cannons and tnt grenade without lagging the server.

I know this is not ur issue just thought I would let u know in case ppl ask in future. War conflicts with Armageddon

It looks like your cannons file got corrupted. Try moving aside plugins/Armageddon/cannons.ser after stopping your server.
