Crash due to Slimy Saplings (another victim)

I, too, get a complete minecraft freeze when I log in. It was manageable at first because I could still do stuff for 10 seconds; now I'm completely stuck the moment I can move after logging in.

I checked the original thread, and I'm 100% sure I saw a Slimy Tree in my neighbor's (suchtie/cmartinez) yard right before I became unable to login.

Here's the last part of the message & errors log right before minecraft becomes unresponsive:

And IndexOutOfBoundException in Tinker's Construct followed by an endless slew of 'Already Tesselating' exceptions.
