Does the issue occur in the editor or during gameplay?
If it's a gameplay issue, please specify which movement system and camera type you're using (free movement vs. grid movement, third-person vs. first-person) or N/A if not applicable:
Briefly describe the issue you're experiencing:
If you're using custom fonts, changing the project directory path breaks widgets
Are there any errors in the in-game debug console or external console window?
screen taken from the tests performed by Slayer (thank you)

Provide the steps necessary to reproduce the issue:
- create a bare bones project
- creates a custom 10x10 widget with only 5 inventory slots in the last row
- add a custom font to the project
- set it as for the title of the widget
- assign to “bare_justin” the custom widget as inventory
- close the project
- close the editor
- move the project directory somewhere
- reopen the editor, find the new path and open the project
- the widget will be “broken” both in-game and in the editor
Provide a download link to the bare bones project (strongly recommended if it's an in-game issue, since this helps significantly when attempting to reproduce it; the report will also be given more priority in this case):
Additional Notes
Slayer ran tests on this report in the help section of the Discord channel and posted the results of his analysis.
He found a workaround to handle the problem, I paste the solution below:
The issue appears to be that fonts once set, get location locked, so when you move the project, it's still looking at the old location for the font.
There's an error saying as such in the terminal window when you open the project. ERR_CANT_OPEN (see image)
I further confirmed this by moving the project back to the original location without doing anything to fix it, and it worked again.
It's super easy to correct once you have moved it though, even if it's a slight hassle depending on the number of widgets.
Just switch the fonts back and forth (default, then custom) and save the projet and now it will work in the new location.
