Wielding Executor crashes the game for a Weaponsmith
Any hand or missile slot
I got Executor from a greater vault in the FGJC. I suspect it has to do with the level 25 class skill of Weaponsmiths adding {<metal>} to all metallic items. Previous game with a Hurthling thief I also got the jet-black battle axe, but I was able to wield it without problems. Version 57 without NotEye.
On a side note, the automatic backup creation is working just fine. I have saved a copy of the backup file in case it is required.
