Just 2 days ago (October, 28 2018) while I was practicing a strategy versus an AI, I ran into a weird glitch in Age of Empires 2 “UserPatch 1.5 / Wololokingdoms 5.8.1” where my villagers were actually able to climb a ‘V’ shaped cliff. I first thought it was just a one-time glitch therefore I restarted a new game with a different map generation and send my villagers straight to every cliff I could see then I succeeded to replicate the glitch especially with ‘V’ shaped or long cliffs.
Above is video demonstrating how I was able to walk through the cliffs all the way to the top.
Has time come for villagers to climb cliffs or this is just a glitch, huh? Please feel free to test and let us know.
The nasty part is when a player thinks that a cliff is forming a free wall for him while in fact it is a passage for an enemy to build secret bases and smuggle units through without you knowing.
How to protect yourself from this glitch?
Simply placing pieces of palisade walls at the end of the ‘V’ shaped cliff or walling the cliff should do it the trick.
