Chinese - Extra Materials Technology still repairing enemy walls?

I was in a skirmish as French vs Chinese (Hardest AI) and I noticed my walls being repaired by the Chinese “Extra Materials” technology for their outposts/towers. There was no repair icon above the wall segment, but it was definitely being repaired.

This was supposedly fixed in patch 8324. I never tested it then, so I don’t know if it either regressed or was never fixed.

Build: 5.0.9369.0

Thank you for the report @CrackingMusic84. I’m not sure either, but will look into it. Appreciated!
