DM Eddie said: I've already lost the exact sequence it happened with, but I do recall that it was in a macro that also asked for targets for /fx and !token-mod so maybe that is why it was throwing the error. I can't properly provide the context now so I guess I revoke the issue. Ah. I think the issue is that ChatSetAttr doesn't play well with other API scripts in a macro. I've tried many times to create macros that use both ChatSetAttr and Tokenmod, and they always fail in some (weirdly irregular) way. One will fire, the other will fail silently, and vice-versa.
