Where you select your CP, there is none! I didn't do anything with the CPs!

How many command posts do you have? You have to specify each one in the lua.

I didn't add any!

So you still have the four original command posts, and you haven't renamed anything, right?

You don't have to specify any command posts, only if you want them counted during Conquest. One of your AddCommandPost( XXX ) is wrong. It could be from a typo in your lua, a typo in ZE on the name of a CP, or a CP was removed and you didn't update the lua.

For example I had
cp1 = CommandPost:New{name = "cp1"}
cp2 = CommandPost:New{name = "cp2"}
cp2 = CommandPost:New{name = "cp3"}
cp4 = CommandPost:New{name = "cp4"}
cp5 = CommandPost:New{name = "cp5"}
cp6 = CommandPost:New{name = "cp6"}
instead of
cp1 = CommandPost:New{name = "cp1"}
cp2 = CommandPost:New{name = "cp2"}
cp3 = CommandPost:New{name = "cp3"}
cp4 = CommandPost:New{name = "cp4"}
cp5 = CommandPost:New{name = "cp5"}
cp6 = CommandPost:New{name = "cp6"}

I did not add any CP's.

Maybe a bad munge, try a manual clean and see if that helps.

If that doesn't work, post the LUA.
