The liquids shader in the newest map: akutadm2, conflicts with the liquids shader in maps: akutatourney8, and akutadm1. This shader is used therefore radiant doesn't sound off a false error the texture is missing even though it's not. It still works when using another shader name, but sounds off a false error which is why I used the liquids shader. It does not over ride the original game shader. However, MODS such as Metal tech and others do. That is why they are not advised to be used with your game.
I have remedied this issue with the AKUTA Map Pac. There is no conflict with any map within the newly updated Map Pac. Please update your Map Pac if you haven't done so to take advantage of this new change.
