Upon entering the 24/7 in the strip, I went through the ground and ended up in a parallel universe where cars (and interiors) don't exist. Created another character to test, and it happened again.
Can't seem to attach the pics here, so:
I first spawned near the Four Dragons Casino. No problem there. Ran further up the strip and the game crashed next to stores (Binco, 24/7, etc) near the Emerald Isle. Now, everytime I log in, I immediately crash just like Vinnie.
