Larian Studios Forums Divinity: Original Sin 2 - The Modding Dungeon Divinity - Original Sin 2 - Modding Troubleshooting Cannot update already published mod

in case you have no option left, try making a new mod and copy over the assets from your actual mod over, sure you would have to recreate the steam page, but thats all i can think off at the moment
(hope its a newish mod where you dont lose too many followers)
