when ck quit he said he was releasing his scripts as .cts because he didn't want to deal with people spoofing them, and then bothering him to fix them. Basically, if you use it, and it doesn't work, deal with it
As far as source, all his "free" scripts should be around in .ts form, as for his combat pack, I don't recall them ever being released as .ts
I would wonder if he even still has them laying around
Can't lose anything by asking though.
