I've had this via the other popular digital distribution platform for years and so it's a comfortable 5/5 for the mod. Wesp5 is a true legend for creating and maintaining it. However the GOG experience is severely lacking. It hasn't been patched properly with many files missing from a properly-patched copy (that's why we're getting "Node Graph Out of Date" errors on the GOG installs). This early in to the GOG Mods project is when I'd least expect to see this sort of issue. I've reported it to the dev who said he'd also noticed it and told GOG about it weeks ago. This is an active mod which should be getting frequent updates anyway so it's simply unacceptable. I don't want to dissuade anyone from buying it hence I am keeping it a 5 star review but GOG, at time of writing, need to step it up.
