I’d hate to ask the obvious questions, but you say no new names on towers…did you have towers loaded with arrows and scholar lens walls?
If not that, if even one spot is open and not floored within walls, someone can escape rope in.
If not that, if you have any road tiles inside, some people have been known to abuse the mechanic in which they can “relog” and appear inside your base.
And finally, if you were in tribe, towers won’t attack tribe mates. Hate to think a tribe is robbing fellow members, but it happens =(.
Anyways, I hope you do come back, as I’d like to see the game grow, and I hope you do come and at least see the possibilities I could list, I’m sure there’s more ways I don’t even know about.
