I believe you have a limit on how many Creeper Egg Explosions you can use a day. Me and Jandal used 5 each and now we can't use anymore. kzhalps used 5 and now he can't use anymore. Thats probably it.
As far as testing went, explosions don't seem to do block damage right now. It'll be fixed the second it's found out as to what's going on.
Our clan and some other people told Cyp and told him about the problem. Creepers and TNT should be working now.
