OK, after reaching L20 with a Runemaster, I’ve been running into constant crashes, usually after 30-40 minutes, sometimes after one hour. Here’s a link to the crash log: Initialize engine version: 2019.4.40f1 (ffc62b691db5)[Subsystems] Discovering - Pastebin.com.
Since I only play offline, it’s not a connection issue. I believe this is character-based, as my other recent characters - Marksman, Beastmaster, Necromancer - all made it into L30 and beyond with no problems.
