This patch will fix every single issue in the caves.
There seemed to be a far greater malfunction in Darkmoor, such as disappearing doors and crashing cave levels.This patch will fix every single issue in the caves. Apologies :)
Patch only includes the Data folder, so you don't have to download a huge 300mb package at once.
How to patch:
1. Replace the old Data folder in the game directory with the new Data folder in the zip.
