Does it give you a line number? If it does, you can (possibly) narrow it down to what script is the problem by using ScriptInfo -- if your sandbox will reboot and stabilize long enough for you to run a command. If, once you have ScriptInfo installed, you can get your sandbox to boot up to a stable session, run this command (substituting your line number in place of 1000): !scriptinfo 1000 The catch is that ScriptInfo uses an "opt-in" method of script registration, and some of the older scripts haven't implemented it, yet. If ScriptInfo can't identify the line as belonging to a particular script, it will at least be able to tell you it is x-number of lines before this one or y-number of lines after that one. That can help you narrow down which script is the problem. If it is a script (not a character sheet) and you can narrow it down this way, it might be easier for other people to test in their own games and to report their results.
