I expect a last minute crisis at this stage to be completely unrelated to the game code. The game has "gone gold" as of several weeks ago. I'd put my money on some infrastructural issue with getting the downloads ready for Steam/GOG, or updates to marketing images, etc.
Larian is known for tweaking things until the very last minute, see the DoS2 GDC talk. It wouldn't surprise me if a last minute change in a last week crunch situation caused some crisis.
