And ... no good results go unpunished.
So I got an invite to join a group in Atlas while on Redlynne.
Having run through a couple MSRs without only a few crashes to desktop when attempting to /unloadgfx to force garbage collection on memory, I was thinking things ought to be okay.
All kinds of world geo textures were failing to load properly (most notably, trees in Imperial City, along with most of the building exteriors and interiors as mentioned above), but at least the game client was running.
Anyway, I zone into Atlas from the RWZ just fine, exit the Vanguard Building when the team lead decides to teleport me a couple hundred yards and ... CRASH TO DESKTOP.
Log back in, select Redlynne again.
Loading Atlas Park and ... CRASH TO DESKTOP.
Repeat.
Repeat.
Repeat.
Repeat.
At this point, I decide to try one of my other alts parked in Pocket D.
Load just fine.
Do a lot of work rearranging windows around for the new screen resolution.
Get everything positioned right, save the new window locations as a default.
Switch to my Soldier of Arachnos parked inside the Arachnos Building in Port Oakes, load up the new window settings that just got saved. Everything's looking good.
Go outside ... CRASH TO DESKTOP.
Relaunch Sweet Tea. Validate all files.
Launch Rebirth. Log in. Select my Soldier of Arachnos. Load into Port Oakes ... okay, good, made it.
Run down the steps, turn right on the street below the hospital to head on over to the West Ferry, run just past the hospital steps up and ... CRASH TO DESKTOP.
Log back into my Soldier of Arachnos. Load into Port Oakes and ... CRASH TO DESKTOP.
Repeat.
Repeat.
I don't know WHAT it is ... but something in the environment of these locations in Atlas Park and in Port Oakes is absolutely FATAL CRASH LETHAL to being able to remain connected and play on 2 of my 3 characters now.
I'm hoping that a simple GM "move character in Atlas Park to new SAFE location" (inside the Vanguard Building) and "move character in Port Oakes to new SAFE location" (inside the Arena) will be sufficient to resolve this issue.
Otherwise, I'm going to be stuck staying offline from Rebirth again.
