Cannot save document error

Script Debugger Beta Testing
#1

I’ve been getting this error message when I try to save a script.
“Cannot save document
invalid component instance (badComponentInstance:-2147450879)”

Script has a lot of myriad tables calls.

Any suggestions?

I’m now encountering this also after some weird crashes. No external code involved except scripting additions and foundation framework.

Me three. Just the same as Ed Stockly’s remark.
Mine is an 1802 item nested set of records. Each record has eight fields.
