  While mining I ran into a invis block that I cant break but cant run past. When I try to put something in its place it crashes the client with the error of
• java.lang.NullPointerException
• at xe.a(World.java:1294)
• at xe.a(World.java:1100)
• at ln.a(EntityLiving.java:2222)
• at ayt.a(EntityRenderer.java:243)
• at ayt.a(EntityRenderer.java:1004)
• at ayt.b(EntityRenderer.java:949)
• at net.minecraft.client.Minecraft.J(Minecraft.java:884)
• at net.minecraft.client.Minecraft.run(Minecraft.java:779)
• at java.lang.Thread.run(Unknown Source)
  
  with out the bullets.
  
  
  I pulled up the world in mcedit and it shows the block ID of 246, I also searched all the config files and I'm not able to find a block id of 246 so I can see what mod is causing my issues.

Figured it out, I enabled ore generation from IC2 to get more copper and tin and the client wasn't reading it correctly. So I updated the client and everything works correctly now.
