This is a serious Glitch, that all players need to be aware of. From what I understand, only two admins so far have dealt with this bug.
1) Upon exiting Mihails Voodoo Bar
2) Upon exiting City Hall, LS
Symptoms:
The world doesn't spawn, similiar to what happens with the UAV's /Recon sometimes. The only things that spawn are a few streetlamps and the mall directly East of LSPD.
Other things: Also the Yellow Marker inside City Hall hasnt teleported me to a City Hall exterior anymore, takes me to the interiors original position, in LV.
Ways to correct this IN-GAME:
-Correcting includes using /tv off (If admin) (However suffer the spawnings of a fat grove)
-Entering a public-access building (IE LSPD, or 24/7 nearby) However, you're minimap may become un-adjusted correctly, and your maps will show you as above water. (/tv off fixes this, admin only, otherwise stays glitched till respawn)

I am sure that the Scripters are already aware of this issue, however this is more of a warning to players. If you have seen this bug or know anything about it, please, feel free to post

NOTE: For anybody interested I have videos of this occuring at LSCH. Will compress them and upload them within a day of this post.
EDIT:
I am currently conducting Non-admin tests for $$$, to see if it is a bug based on Admin commands. I pay $200 per testee. The test consists of
-Entering LSCH.
-Exit on yellow marker.
-Enter LV yellow marker.
-Type /Exit
-Assistance to nearest Public-Access building (If needed.)
Results:
World Glitched: 1
