Here is all the bugs I have encountered during this version, sorry if this is annoying

1.When you try to use the angel statue near Urbus, you get an error when trying to teleport to the town of beginnings.

Unable to find file:

Audio/BGM/Sorrow's Cessation (I posted this one before sorry if your already working on it.)

2.When you try to leave Tolbana from the south you get an error saying

Unable to find file:

Audio/BGM/Sorrows's Cessation (Same error as the one above)

3.When I tryied to backtrack through the Urbus mountians I got an error saying

Unable to find file:

Audio/SE/step2

Also as a extra question, Why is it that my game lags alot? I can play Skyrim with mods but sometimes when I enter a certain area in this game I have to quit and start it again for the lag to stop for a minute before it comes back, do I need a certain software or is this just not fixable?

1)I saw it before, but honestly it doesn't make sense, the BGM is in the game files, and I can't seem to recreate it. Works normally for me.
2)Same thing.
3)Can you provide a screenshot of any area next to that? There's a lot of maps in the mountains.

Probably related to Khas'es light script. I've had the issue for a while. It triggers in areas like dark caves, where torches provide their own light. Honestly it's a pain.
