The main problem I'm having (maybe related, maybe not) is that my jets keep cutting off, even when I'm holding the button constantly. Sometimes they work for the whole bar, but usually it goes on and off. It happens more if I'm dropping, which has already led to a number of falling deaths.
I tried reinstalling, which didn't work. Can anyone confirm this as a bug, or is it just happening to me? It just started in 1.4.1 (everything was fine in 1.4). Doesn't matter if I use the patch, or make a fresh install, it still happens, and it's bugging me to no end.
