Unable to save build (PoB is using / instead of \ before the filename)

What is the expected behaviour/value?

After importing a Pastebin URL into a new build, I should be able to save/save as the build.

What is the actual behaviour/value?

After clicking the save/saveas button and entering a filename, I get the following error:

Couldn't save the build file:
C:\Users\smoker\Dropbox\Home\Games\Path of Exile\Character Builds/tempi.xml
Make sure the save folder exists and is writeable.

How to reproduce the issue

• Import a pastbin URL into a new build (I'm using https://pastebin.com/qMmKksb6)
• Click either the Save or SaveAs button at the top of PoB
• Enter a filename (I'm using "temp")
• Click the Save button

No se indica ningún archivo de origen ni ninguna prueba. Reproduce la importación desde Pastebin y, después, prueba Save y Save As en Windows; sigue el rastro de dónde se combina el nombre de archivo del build con la carpeta de guardado. Se considera terminado cuando un build importado se guarda correctamente con separadores de ruta de Windows coherentes.
