**Issue: Accidental Weak\_Map Allocation Stuck in My UEFN Project** I was working on a leaderboard system for one of my UEFN maps and experimented with a **weak\_map** data structure. Before getting too deep into it, I realized weak\_map wouldn’t work for my needs. However, I left the declaration in my file, thinking I might use it later. Unfortunately, I didn’t realize that once I published that version, the weak\_map allocation would be permanently tied to my project. Since UEFN only allows two weak\_maps per project, I really don’t want my early prototype taking up one of those spots—especially since it has never been used and holds no data. **My Question:** Is there any way to remove the unused weak\_map from my project, either through Unreal/Epic support or some other method? Since it’s never been accessed, there would be no data loss—just a cleanup of an unnecessary allocation. I’d really appreciate any guidance on this. Thanks in advance! ---

Quick update, I attempted to enact a theory I came up with. That being to roll back my published version to one without the weak\_map. I was able to validate the project without the weak\_map afterward. I’m seeing now if publishing goes smoothly. ---

Interesting, If you actually managed to reset weak\_map allocation that would be huge, write if it ends up working or not. ---

That’s just lovely. Hopefully they add some official way to do something like this too ---
