Simply Jetpacks would indeed be a very welcome addition to the pack. Since it's very staged, its also easy to add quests for this pack. Just don't make me put armor on the lower tier jetpacks cause you can't upgrade them to higher tiers as far as i'm aware...
Juster was a nice little cat, to the disappointment of my girlfriend with whom i'm playing this pack, he disappeared after a few days
Hope you don't mind i used a cheat-sheet from the config files for all the agriseeds crossbreeding
Jetpacks are already added in the new update (which I think I will release very soon)
Hehe, just like in real life He disappears and suddenly reappears, but he is an old cat now. He is the same age as me, 17. He can be compared to Bilbo. Suddenly he has gone off to some adventure and doesn't return for a long time. Maybe you see him again if you are lucky
You can do whatever you want when you play the mod pack. Just make sure you are having a good time!
