My bard has been crashing to desktop, with no error message at all. DBG.txt showed the "failed to create textures" which is discussed in the post
here. While the issue there seemed to stem around the guild roster, after seeing this post, I unloaded mq2dpsadv, and have had no crashes.
I've gone through a boatload of searches, both on the official DBG forums, here, and google. The failed to create textures seems to be something fairly common, and I after all the googling, I don't think is related to the crash(es).
Oddly, my crash happens ONLY on one toon, a 115 bard running KissAssist. Same account, I have a 115 enchanter, and can run him (on KissAssist) without problems (over a period of about 60-70 minutes). Loaded the bard back in, and crashed within 5 minutes. Reloaded, crashed again within 5 minutes. Again, mine is a crash to desktop, with no error message. Toon stays "active" in game, and have to boot him when you log back in.
I deleted all .ini files, ui files, loaded default UI on the bard, deleted his /advl settings in the EQ folder, and nothing seemed to work. This morning I unloaded dpsadv, and have been online for over an hour, fighting in the same spot as last night, and haven't crashed (using the same KA file as before, and having reloaded a downloaded custom UI piece for the player window, everything else remains default). /shrug - here's hoping it was just the plugin and not something more involved!
