Okay, guys!
Now, the tech "Piracy" requires "Naval Warfare" to be discovered. Ancient Pirate units now need a "Smuggler's Shanty" and/or "Pirate's Cove". The modern ones, I don't know, maybe we need some buildings for them.
I'm not sure, if the strengths of the "modern" pirates and "hunter" units need some fine-tuning?
Btw, Hydro? I think it would be more logic if "Smuggler's Shanty" and/or "Pirate's Cove" require "Piracy"... wouldn't they?
@ DH I don't know how to fix a CTD... in that issue I'm a nooby. What causes it in general? How can I fix it?
Post a save game where it will CTD on end-turn (so presumably the one you complete the research of the triggering tech) and I'll debug it (assuming it CTDs for me to).
