--- Comment #4 from Ker noa blue-t@web.de --- https://bugs.winehq.org/show_bug.cgi?id=49287 uses the same engine and has the same symptoms. Repacking the assets into a correct unityx bundle without the offending GameIntro.mp4 Codec: H264 - MPEG-4 AVC (part 10) (avc1) Codec: MPEG AAC Audio (mp4a) is a heck of a lot harder than just deleting 2 files in a folder. I would consider it to be the same though without trying.
