My first attempt of using the new live linking feature causes SW13 to crash. With SW13 and KS4 open (live linking is ticked in KS) with the linked files, clicking update with the plugin SW13 causes SW13 to crash and the KS4 file doesn't update. Maybe the file size is a problem with the .bip being 2Gb, I'm not sure.

Can you share this file with us and tell us what you are trying to change? We will try and reproduce it here.
I have sent the two files to your email.
Great - thanks. We will take a look.
