It seems your method for adding psionic power tags to the class isn't working when they are a tertiary ability.
The ClsAllowPs.<powerid> method doesn't seem to be working on my newly created mythic ability that is supposed to give access to a disciplines powers.
Ok, I was able to put in the following script to get the powers to show up, but it now gives the dynamic candidate expression error message that we got above:
I got the command from your Ultimate Psionics component.str file and modified it for a specific discipline. (cPsiSeer used to equal "?" in the code)
linkage[table].field[cPsiExpr].text &= "|" & tagids[psiClass.cPsiSeer,"|"]
Any ideas? -- Nevermind. I needed to add a psiClass.cPsiSeer tag and the code you had in your new component.str file surrounding it. It works without getting an error now.
