Yes, I'm not issuing anymore patches for Version 3
Fortunately, I am putting all my efforts into making Version 4. The Irish culture leak has been fixed and seems to be working fine in version 4, which I nearly have a fully working descr_strat to test. (P.S..the End product is still a while off).
The Irish stacks that appear was supposed to simulate (or perhaps stimulate...funny how the words are so similar) the Irish rebellions which led to the fightback against the Norman invaders. Truthfully, I never tested this and just relied on the theory of it to work...sorry
This is located in the campaign script which is fired when a game starts. There are 4 Irish Rebellions added at 10, 20, 30 & 40 turns.
