Still have ZERO idea what the problem WAS, but I've been trying periodically (and failing) My "Test" was to run to the East road, Kill the first set of mobs, go right and kill that first set of mobs, and then it would be "gone" (every time)
Well, today I ran to the East Road, killed the first set, and then went on the do the entire Henredon Run - with NO problems!
Haven't changed anything, tweaked anything, or made any discoveries. It just works again - just like it stopped working for no reason. The planets must have fallen back into alignment or something.
What I found is, that if I am playing a character with changed appearance like say yukio, I am very likely to crash in town for instance, not always but very often. So far I found no solution for that, but to live with it. On other areas/runs it works fine.
Interesting, if when I go through the docks to town gate I get a screen flicker it usually indicates an imminent crash to desktop, I'd assumed that it was graphics card related. Sometimes I also crash repeatedly with the same character on login and the only way to fix it is to go to another server successfully get in then relog to the one I was having issues with.
I routinely experience crashes when transitioning to town upon initial login. No character edits were made, base race was God-Blooded one on character and Half-Celestial on another, no equipment was modified. The exact same thing Chainlink described. A screen flicker and then boom, gone.
Glad things have resolved for you Moe and welcome back.
