Always!
Also thanks for the hint. Stripping worked!
I then reimported the 1.18 files but still have stormwrack and monsters of fearun in the list twice... would reimporting even help there? or should I do something else? is it even an actual issue? do the entries interfere with each other?
Sorry. I should have been more clear. I have fixed the issue, but it will be in the next release. For now, you can select both to make sure you aren't missing anything. After the next release you'll need to do the Strip Missing Sources thing again. Apologies for the inconvenience.
