Boats were reworked, and all missing masts and sails were fixed. Proxy masts/sails apparently were glitched in vanilla and none of the boats have them, Nitpicker's Patch doesn't fix this. Also fixed some invisible boat proxies.
I've been waiting for three years for this to be released. Im so glad it might actually happen sometime soon. Hopefully. Would it be possible to get a WIP release. Even just getting what the screenshots show would change the game dramatically for me.
gonna take a wild guess here but did you try to edit envs?
cause statistics show thats #1 reason for broken gpus among witcher 3 modders. i would just stray away from it and instead leave it to experts. They developed some special strategies to edit envs like they surf the ways without breaking them.
