ACG Arena 2.5.6 map fix for 1.26a by Kroda https://drive.google.com/file/d/1VV5Z0jVOs5IPhxHeWsYNPHUMfoNWSXwJ/view
ACG Arena 2.7.55 (Unstable, not perfectly fixed) https://drive.google.com/file/d/1Fgjagpe-bSy3ivn5A49uLsUsJrys-HJu/view
I wont be fixing ACG for 1.26 anymore since there is a way to play with netease natives. (I still make some gameplay edits to the latest ACG versions, but those are unofficial so i'm not sure i should post them)
