Once you try another cook/push to Steam, you can edit \steamapps\common\ARKDevKit\ModTools\ModConfigs\YOURMODNAME.vdf
Then make sure “publishedfileid” has your Steam mod ID in there.
It might be worth doing a full re-install of the devkit from Steam, and re-adding the github engine.
I had this weirdness where I was getting 1fps / low frame rate in the Unreal Editor PIE… tried everything… eventually re-installed to fix.
