Ever since 1.6.1 and 1.6.2 I've been getting weird lag issues. When I first started making my house, there was no framerate issues what-so-ever but when I got onto the roof-phase of my building, I started to lag. When I finished my basement when I walked and opened chests I had no lag issues; However when I placed or destroyed blocks my 55FPS Went down to 2FPS and double placed blocks. I do not have this issue in single player and was wondering what the issue was. I went on another laptop to see if I still had the error with framerate and again, in singleplayer everything was fine and in multiplayer I dropped to 2fps whenever i placed or destroyed a block. If this is my error, like internet/.minecraft please tell me. I've already redownloaded minecraft about 4 times to see if I just had a user error. I have no idea what's going on and I can't play the game with 2fps everytime I place or destroy something. Thank you for reading.
