Is it possible to remove too much material when chasing bb threads?

I am sorry if this is the wrong sub-forum but you guys know metal-work and tolerances better than anyone on the forum.

Last year I bought a brand new Surly Karate Monkey frameset and chased the threads using the super awesome Park Tool tool from the shop I worked at. It was my first time but I am a perfectionist and it took me like 2 hours . I used TriFlo to lube the threads because we didn't have the lube that Park Tool recommends for chasing threads.

I can now easily screw in my external BB by hand. I have never felt a BB feel so loose before. I wrapped about four or five layers of thread sealing tape and this tightened up the BB but I fear that I may have permanently damaged my frame by removing too much material because there is a faint (but noticeable) click while rotating my pedals (even though I have stripped and built the frame with two TOTALLY different parts and groupsets).

Is it possible that I removed too much material when chasing my threads?

THANK YOU FOR YOUR HELP!!!
