Yeah but what expectation could they have had that they'd need to communicate with Bethesda in the first place? The game's been "complete" for several years at this point, and IIRC Skyrim Special Edition (the Skyrim version of what happened here) was both announced in advance and released as a separate game, so mods that weren't getting updates could still function. In light of that, it seems reasonable for the developer to expect advance warning at least in the form of a press release prior to the update being made available. Should they have reached out every week asking whether Bethesda had any plans to update a 10-year-old game?
