Hi, I'm sorry to hear you're having issues. Does this happen after restarting the game as well? If so, please provide me with the log file and I'll see if there's any relevant errors there. The log file is located at "%AppData%\Godot\app_userdata\Feraline\logs\godot.log"
If you open your file browser in Windows, and click the path bar at the top, you can copy and paste everything inside the quotes above and press enter. It should open the log file.
No worries! I've been trying to find ways to reproduce it, trying the game on a few different devices, and storing the game in different locations. I can't seem to re-create it. So the character shows for a second then disappears? Is the character the only thing that disappears? Any information that may help me reproduce the bug would be super helpful, I'm a bit at a loss here.
You could try running the game as administrator, but there should be no reason that would be necessary, and I understand if you would rather not try that.
I released a new build (v1.0.1) where I changed a few things at random that may be related to character visibility. I'm still not confident it will fix it, because I can't reproduce the issue myself. Please give it a try and let me know if the results are any different, if they still aren't, would you mind sending me your PC specs? If there are similarities between your specs and the other person's, that could be a lead to follow.
