Humm, I tried your mods a year or so ago with a "Tactics" install using BWS, Trilogy. OMG there were so many problems......such as...
Rothgars text showing up in Hobgoblin battle cries.
Transistions in Hand Broken
Transistions in Mage School Broken
Once the time dude sent me back to current time, key story creatures were not spawning to advance story line....(so long ago I cant remember names)
Orc camp for Dar not spawning
So if I am reading this correctly, these are fixed? And it is fully compatible with a mega install? (meaning there are only small bugs, no game advancement ending bugs)
