I play minecraft in singleplayer survival mode. I can break block just fine around my spawn point, but when I get far away from it I start running into trouble breaking blocks. I can break the block but the block reappears right away, it can take several tries before the block breaks and even then sometimes it doesn't happen. I have tried restarting my computer, figuring it might be a memory problem but that didn't work. I also did a clean re-install of minecraft and the mods I use but that didn't work either. I don't know what to do to fix this, as everything I thought to try hasn't worked. I am using Windows 7 64bit.

These are the mods I am using on Minecraft version 1.5.2:

forge 7.8.0.712 for 1.5.2
Magic Launcher 1.1.4
Optifine 1.5.2_HD_D3
Code Chicken Core 1.5.2
NEI 1.5.2
Cube Bots 1.5.2 v1.4.3
Twilight Forest 1.5.2 v1.18.0
Thaumcraft 3.0.5C for 1.5.2
Thaumic Tinkerer v1.0.3
Rei's Minimap 1.5.2 v3.3_06
The Camping Mod 1.5.2 v1.0.1d
Drzhark's Mo' Creatures 1.5.2 v5.2.2
GUI Api 0.15.6-1.5.2
CustomMobSpawner 1.5.2 v2.2.1
Damage Indicators 1.5.2 v2.7.0

I found out what the problem is, it was the Cube Bots mod. I removed that and now it works.
