Postal, you seem to be right about the fixes being mostly for ONP. I've been looking for stuff to fix, and a lot of them are map-specific. Thankfully, a lot of issues can still be fixed with a mutator. Map editing is the very last resort for me. Heres a list of stuff I still need to add into the mutator:
NP09Silver: Theres a lift that only activates once, which leaves people stuck if they do not get to the lift in time. This should be a simple fix of setting that mover's bTriggerOnceOnly to false.
NP14MClaneDrPest: Buggy playerstarts. These fail to work most of the time. This is bad because it is quite a run from the starting area over to where these playerstarts are. Along with a tough area where players have to dodge lasers. (Many players end up leaving thanks to this.)
NP08Hourences: The lifts work, you just have to trigger them too many times. This one isn't a bug, just something that annoys me. There are a few lifts at the start that are set to TriggerToggle, which means players have to hit the trigger to make the mover move. This just adds some unnesessary waiting for any players left behind. (Players have to hit the trigger once to call the mover back, and then again to ride it back up.)
All of these seem to be pretty simple to add in, I just didn't get to doing it yet.

I'll keep you guys posted on my progress. Any ONP players out there, feel free to add any suggestions.
