So far so good
Now the problem in plugins
Actually since the 1.2.3 update my client really hates MCServer, I get incredible FPS lagspikes and sometimes the game eventually freezes O.o
Nothing of that sort on my end
But, hey, it seems we fixed the Boo-Bug

Boo-Yeah

Nevermind I think it's a memory issue, I gave Minecraft more memory and it was fixed. I had this problem before but I did some dodgy version switching and my setup broke, so I used the default .exe file instead of .jar with parameters and it was laggy.
