How do the autowin victories occur?
For example if you move across map with no troops and someone attacks you. Are you then instantly teleported or does it take 24h to lose? Are attackers locked in place at all?
There are no autowin victories, unless someone attacks you with much less troops, in which case it is an auto lose for the attacker, the defender can never autolose. All other rules apply.
Therefore it is probably better to have a caravan with many troops so that way fewer people can actually engage you.
You can defend with 300 against 10,000, but you cannot attack.
You cannot carry more than one trade good at a time.
You should already see their night time if you can see the option to "attack." There is an option to cancel if you make a mistake.
