STORY: Okay... I decided to actually play 100% Legit Survival Single Player after many months... (I had rage quit because my world had broken due power outage, world went poof gone :/ ) I made the world and everything.. I smashed some keyboard keys and got this seed, (It's pretty good for beginers like me. Lots of exposed iron and coal everywhere: 113497860 ) Stuff and blah and stuff... ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Problem: It's lagging as if it where some sort of server lag in SMP. I'm trying to break any block and I need to destroy it around 5~ times for that block disappear and go into my inventory. I re-created the world 2 times and same problem. I made another world with the same seed and same problem. HALP MEH! BTW: I'm playing on 1.4.2
I also closed and re-opened minecraft, the problem still persisted. The only mods I own are: Optifine World Download (Something like that) I can play on the EMC servers fine.
Ive got 10 mods (Or semi mods) and dont get lag at all. Other than removing the downloader mod, I dont know how to help.
