Ok this is strange...I accidentally turned Infinite HP on (was trying to turn on Inf Willpower), though I didn't notice at the time. I was in Chapter 2, fighting the waves in the Vault. Went into avatar mode (Yeah, I know, not what it's called) and kept getting the "Not enough rage" error, couldn't do any of my attacks, even though I'm pretty sure that form doesn't use Will OR Rage. Eventually popped out back to human form, finished it off. After the cutscene at the end of the fight when you get out of the vault, I tried returning to town (pressing "T", the bar would fill up a little, then stop completely. Also, the music stopped too! I eventually just took the waypoint back to town, no music there either! Finally looked over at the trainer, saw Inf HP was on, turned it off, and the music came back lol. I could also port again. Weird.
I've just been running with god mode Force Shield, so I haven't used the Inf HP at all. Just this one time since I turned it on by accident. Really strange that it prevented me from porting to town as well as turning off the music...I mean, the music kicked in literally as I turned the option off. I couldn't get it to reproduce the effect either. Just thought I'd note it here.
The options I had on, which I've had on since this trainer was updated, was the faster attack and spell casting speed and 100% crit, as well as locking Force Shield regen to 10000 and time to start the regen at 0.01. I haven't had any issues with these on for hours. It was just when I accidentally turned the HP code on that I ran into the no porting and no music issue, but again, I haven't been able to reproduce it - although I also haven't gone through a cutscene again with it on yet.
