I believe I’ve managed to fix an issue in the engine where UMG Widgets are not destroyed for players on Server Travel / leaving/opening a map. The code is here: A new, community-hosted Unreal Engine Wiki - Announcements and Releases - Unreal Engine Forums
I’m not sure if in that form it’s suitable for Engine code, but if it is, I’d like to submit it as a Pull Request. Trouble is, I haven’t the first clue where to start. How can I go about uploading the fix and submitting it?
