One terrible work around is to migrate the map to a new project every times this happens. Doing so seems to fix the issue for a day or so, but eventually it pops back up again. ---

Also migrated an old project to a new one yesterday. I had to replace **all** verse devices in the map because they were not recognized, fortunately it’s a small prototype, but on a large scale project it’s not feasible. For now, pushing verse changes works … waiting to see if the issue pops up again P.S. 🔮 I invoke the spirit of the Epic staff if you can hear us, we are facing a major bug, please come forward the post has been there for 9 days. ---

Project migration works for me even on large projects using this technique (it’s still not a GOOD solution). > [@How to copy a UEFN project](https://forums.unrealengine.com/t/how-to-copy-a-uefn-project/1236151/4): > > OMG, I got it to work. Thanks for the help and suggestions guys. For anyone else who wants to replicate what I came up with: Backup your original project folder to some far away place, in case things go wrong Copy your original project folder to a new one. (e.g. Copy “d:\Fortnite Projects\MyGame” to “d:\Fortnite Projects\MyGame2”). Go in the new project folder, rename “MyGame.uefnproject” to “MyGame2.uefnproject” Open “MyGame2.uefnproject” in Notepad (or another editor). At the top … ---

Thanks for the tips, seems to be the safer way to do the migration for now! I had used the migration tool in the content contextual menu (it broke the project) There maybe an explanation why the issue reappears on your side, when copying the old content there are some serialized files related to the compiled devices that need to be updated internally. If within a week, the problem no longer appears on my side, the hypothesis will be confirmed. ---

Okay, interesting. Yeah, my approach only fixes the issue for a few hours normally (or at least until I need to cancel my session). A more permament fix would be greatly appreciated (but I also can’t really rebuild the project, haha). ---

Awesome. I’ve also been having no issues recently. Though, I think it might have been partially due to me deleting a bunch of old files. Regardless, seems to be working now! Great! ---

I assume that you have an asset or folder with a forbidden name. If you have something called “AI” in your Editor, rename that.
