Depending on the size of the mods, there are ways to verify everyone has the same mods, and same versions, without replacing everything.
This can be done with a program such as DVDSig
) or ExactFile
to scan your mods folder (..\Documents\Larian Studios\Divinity Original Sin 2 Definitive Edition\Mods), and swap the resulting files to verify; that would identify any differences between the folders (missing, outdated or corrupt mods). For the Steam version, unsubscribing and re-subscribing to mods where there are differences should presumably make sure everything is up to date.
DVDSig is tiny, portable and doesn't require an install, while ExactFile has more features.
Alternately, you could use a program such as Hash
to create a list of checksum values to compare manually (slightly more work comparing, but no file swapping; probably easier with a limited number of mods).
