And that's of course in addition to the prior pop up upon crashing that I already posted the text for.

Edit: Wait a minute, that stuff was actually problems from 2-22-2021 as that's the last modification date of the txt file, so that must have been with just 1.16.2 stock debug version. I ran the DEBUG-BH.exe version several times in the last week and it doesn't appear to have logged any of them, so as of right now all I've posted that applies to this specific problem is the ASSERT text from the popup.

Couldn't you just search your code for "D:\blackhawk-1-16-1\" or even just "D:" and then make those sort of relative lookups instead of the exact location that's only valid on your system?
