Unity Player.log files can be found by pressing Windows Key + R and entering %userprofile%\AppData\LocalLow\Yellow Dog Man Studios\Resonite then OK. The Player.log is overwritten each time you launch Resonite, so make sure to collect it right away after you encounter a crash, or bug. If you have launched Resonite once since the issue occurred, the contents will be in the Player-prev.log file. If you’ve launched Resonite twice or more since the issue occurred, the Player.log file will be gone as it will have been overwritten.
