I posted this on the Rebirth Bugs forum, but would like to know if anyone else gets this error.
Download the nightly build of Rebirth dated 6/14/2017 (if you're not already using that): http://www.dxx-rebirth.com/download/dxx ... 17-win.zip
Now open either version of Vignettes; if using D1 go to Level 15 and if using D2 go to Level 14 (same level). Shoot the first door open. In both cases I get an immediate crash "invalid notside" error. Do you get the same result when doing as described previously?
