The modpack export feature is still bugged, upon exporting, an overrides/mods folder containing all of the mod files (those not listed in the profile's installed mods section on the launcher) is still created. It works as intended if all mods are listed in the installed mods section.
The profile's installed mods cannot detect changes I make manually to the mods folder of the profile in my file system.
(This is faster when I am using version control to allow me to bug fix) This leads to the export feature's manifest.json not containing any mods that I moved manually.
The Twitch launcher was able to detect such changes, this feature was lost with the move to Overwolf.
