I've been fixing stuff I encounter as I play. However I never noted down the changes, so I couldn't tell you all the changes I've made. Most were minor for example: Mom missing a dialog option to start sister's corruption that she had when fully corrupt, but not when enslaved (totally corrupted)
The big one I fixed was for the scene dialog. The variable the script Nergals Advanced Scene Player was set to check was Frames to Wait (103), instead of Dialogue Level (104)
