There was an update recently that stopped the save box appearing when you click close if changes haven’t been made. However, I have noticed this doesn’t appear to take into account script.Source, I have fallen for this a few times now, I’ve made a few changes to my scripts and then pressed close and it closes immediately. Can’t promise it’s 100% reproducible, but it happens, that’s for sure.
Going to be using the Public to ROBLOX button a lot now.
