The exact circumstances for this seem a bit weird - the save I am uploading will have this happen near the end of the cycle. The buff has already started before this save, though the display says its got a full cycle left (see my other bug report). Saves I make closer to the expire time seem not to cause the crash.
Steps to Reproduce
load save let game run until sparkle streaking buff on Rowan expires (tooltip is wrong, it will expire with tooltip saying about 75s remaining)
This issue has been fixed in either a future version or updated in a previous version.
