I was the one that posted the fix on the Zygor site. the no description was the problem that i ran into when trying to fix the waypoint, personally i like the description to say where its going. i tried the call you pointed out carbonite but it didnt give the description as to where the guide was pointing to, which is why i used the TTAZW call directly.
Call it a quick fix so you dont have to worry about adding another pram and the zygor team could implement it easy without having to rewrite a whole section of code to include said description.
Both of you guys make great addons, and together the awsomeness can't be matched
