Hello fellow AoE players!
This is WilliamWololo, wololo-ing your villagers and army and join my wololo.
(Also an insider for AoE:DE beta, and no, I will never disclose any information about beta here 
)
I just played a classic RoR gameplay with UPatch 1.1 R4, and found that AI will try to do something stupid as the screen capture shown, i.e. build something to block its own way.
Just post it to share. I know there is no way to script the AI in AoE1 (or is there any way, actually?), albeit just want to put it here and let both classic players know, and dev not to let the AI do this kind of thing.
