First, i really like your mod, i hated it to switch every time the lappack with the jetpack!
I just downloaded the new 1.13 (1/2) to replace the old 1.13 and i'm wondering that im not flying while pressing space,
is this a bug or im just too stupid to find the new button for flying?
Edit: It looks like nothing works, solar helmets dont charge anymore..
None of the armors abilities will work unless you update forge. I don't know exactly what version you need, but relatively recent. I'll try and get the exact number for you.
