I like to use scripts. In the past, GG was forgiving when a script line calls a variable which is not present. (Which happens quickly when you copy and paste scripts)
But now, GG 5.0233, a script call to a not_longer_present variable results in a serious problem.
If the script is an update script, executed f.e. by a corner command, GG reports a script error continuously. Sometimes I even have to kill the entire process to stop GG.
I believe that the response on an error should not be worse than the error itself....
I prefer that GG just ignores calls to nonexisting variables.
