Is it normal for the mine to cause extreme lag while inside it? I can barely move my character or do anything inside there, but if I leave it goes back to normal, it's the only area where I experience this issue..
Are you playing from Laptop per chance? If so I had similar issue on my PC, and it's caused by how laptops run RPG Maker Games.
I'm also almost sure exactly which plugin is causing the problem.
Fix 1: Here is the current version of the game with this particular plugin features disabled, I'll update the Thread links later with a proper fix that does not disable the plugin. (copy your save folder over)

Fix 2: This require you to fix the issue on your end. Force your PC to use your real GPU when playing RPG Maker games. Long story short > almost all Laptops have two GPUs, with the weaker one being inside the CPU and running light programs / sites. The issue is Win11 considers RPG Maker Games as light programs no matter how demanding they are, so basically your GPU never activates when playing RPG Maker games(you can confirm with Task Manager), and when you add a more demanding Lighting/Fog plugins your computer struggles.
Obviously these two fixes are are not ideal, I'll try to patch it as soon as I can and update the Thread Links
Thanks for the feedback!
