Yesterday's update seems to have messed something up. The inventory change still works, but hitting the space bar causes you to slowly drop. Removing this mod made space work correctly and the inventory change persists until you die.

I'm still trying to figure out exactly where the issue is. There is nothing in this mod that should be effecting the jetpack. It was a heavily modded game so it may be a conflict between this and another mod or ever 2 other mods that only conflict when this one is in.

The reason i am reporting it here is that this was the mod i removed that made everything work right again.
