Project: Paper2D

module was not deleted but renamed to PaperSpritesheetImporter to better match what it does (since there are other importers in engine). I haven’t seen any other reports of issues with reimporting, but there wasn’t a redirector added during that rename. Can you try adding following to your DefaultEngine.ini for your game project?

[/Script/Engine.Engine]
+ActiveClassRedirects=(OldClassName=“PaperSpriteSheet”,NewClassName=“/Script/PaperSpritesheetImporter.PaperSpriteSheet”)

See if that fixes issues you are having and let me know.

Cheers,
