1: Depend on the script. The result of the checker is displayed. what the result is depends of the script. No result i probably displayed for run-time error.
2: You can change a checker to result in error for empty tags and they will be in the script and taggers issues
I have added a extra line to check for empty config on some of my scripts. The code below checks for that
for _,v in Pairs(conf) do
if conf_nr==0 then
3: probably the result of the last script. If one is ok and the other is error it looks like the ok i still there.
I tries it on the mentioned challenge and the ok is not removed on my map if i run the incorrect checker
This is all assuming that i have understand what ganja have told me correctly and i have not missed anything
The problem with checking this automatically is that empty config is ok on some scripts
