so are you pack packing the update 4 to an engine upgrade, so yeah, the engine upgrade won't go to early access before update 4 comes to early access so we will keep the engine upgrade on experimental branch as update 4 drops and then we're going to keep working on that until we feel that they both work and the main reason for that is because we there were a few like things that got way better for some people with the engine upgrade but some larger factory lines and stuff like that didn't get better, they got worse, so and that's annoying we don't want to like push the upgrade that can result in some people playing in early access getting a worse experience we would rather fix those issues before we do that and we don't have time to do that before update 4 launches so that's why we're doing it this way
