I Crash When I Get To A Certain Point?

Hello! :D

So I was playing Wynn (As I often do) and I was trying to complete the level 52 quest "Crop Failure."
However, when I got to the large bottom of the slime cave and I started attacking the boss slime , I crashed, and that happened every time I tried killing it. Then I decided to go and do a different quest instead (Jungle Fever) and as soon as I got 3/4 of the way past the great bridge I crashed, again and again.

Plus, every time I log back in I have been respawned back at the nearest town as if I had died, although before I crashed I am usually near full health)

Thanks in advance for any help! :D

I tried going across the bridge without VBO's at I got to the end then I well.. crashed.
