And I think I have done something weird now.
Everytime I've done a testrender and press "Abort" or "Continue" on the render status window, LW crashes.
The same thing happends when clicking "OK" on the Statistics panel in layout!
If I load in the older scenefile, that's almost the same scene, everything works!
I tried removing everything, all lights, objects, plugins and stuff and still it crashes!
Deleting the LW config files didn't help either.
It's probably the scenefile that's messed up somehow. Perhaps because of Spreadsheet?
Anyone knows what's wrong here?
