GFCScape edited scripts keep going back to default

[Drorkar]

Googled the problem, no help.
So yeah, I'm trying to edit the objects.txt to mess around in singleplayer with unlimited sentries.
However, after I save it and leave it, it instantly goes back to default.

Are you saving them back in with GCFscape? If so, don't.

Are you putting the file in the right folder destination for the tf folder?

GCFScape doesn't actually modify anything in a GCF. You will have to save it directly to your TF2 local directory, which is most likely located in:

C:\Program Files (x86)\Steam\steamapps\[YOUR STEAM ACCOUNT HERE]\team fortress 2\tf\scripts
