It might be because ShadowGaming may be in a DEV team with someone else and the site just turns on a switch when a game is part of a DEV team to show this when two people are working on the same object’s behaviors at the same time even when on user isn’t a member of the team
I feel like I came across this problem too, but I was apart of a bunch of dev teams so I don’t know if it was a legit bug or just two game devs on the same game, but that does seem rather interesting. I feel like when it says that (since you don’t own the game) you can probably select either keeps my changes, or keep their changes and it won’t change anything. At least i think. I never really tried it. If this does become a major problem then grazer might have to be summoned.
