Also, still playing Tlax, seems to be a promotion bug at one point - Cortez is supposed to promote you (to Elite, I think), it freezes.
I get the same bug with Cortez and promotion when playing as a Spaniard. Don't know if it matters if V's army is defeated or not, had it in two games so far. The latter happened on day 16 after the army was defeated and I *think* it froze in the other game prior to his army being vanquished (read earlier in the thread that not asking for promotion until after defeating V might alleviate the problem).
This is the only "bad" bug I've managed to encounter so far, since I presume it disables Cortez from joining you. Though if I can just pile on quest completions and still get him in the end, that's ok I reckon. *EDIT: Cortez joins just fine, though the dialogue freezes when I ask for a promotion both prior and after him joining the party.
Other small bug, probably mentioned earlier:
The peasant women quest for Cortez: The unmatched_try error as mentioned before, also, the peasant women stay in your party. Completed the quest three times in a row without leaving the room. *EDIT: Short term memory is great... anyway, logically, since it fails the try check, it's not required to have peasant women as captives at all for the quest complete, so, it's a freebie at the moment. I had noticed this weeks ago and forgot to write it down. =)
