Need help changing AI errors in TSM

Hi, I want to make the races more exciting by setting the AI errors in TSM a lot higher. But when I change it, it doesn't save it.
I'm kind of new to TSM as I haven't used it before. Do I have to like change the setting, save it and then export it?

Thanks in advance.

You have to change your track 2 times. First when you edit the magic data you press SAVE in magic data TAB, when you have done that you have to press SAVE in the left top corner menu also, its under create a new track.

When done that your changes will be activated

Thanks for the response, but it seems like there's no sudden change ingame.
I've set the AI errors to 999 and even 9999 but I saw no difference while playing.
I saved it twice and replaced the circuit wad and the file (for example) S1CT01.dat in the folder but it doesn't seem to change.
Maybe I have to do something in GPxPatch?

Thats wierd, i set the AI error from 32 to 69 or 99 and i see already alot of mistakes, they miss the corner and go wide, brake lockups, ...

I noticed TSM saves the Magic Data file seperate as "default.tmd"
So if I replace the Track (wad) file and the (for example) S1CT01.dat files, the Magic Data would still not be updated.
I'm obviously doing something wrong, lol.
Also, where are the Magic Data files of the tracks in the first place? Or are they build into GP4.exe?

Thanks for the help anyways

Never mind, I fixed it. I noticed I forgot to do "Load Tracks". As simple as that. I was putting all files in manually, but it sets it all right automaticely.

Thanks for the help
