Guild Wars 2

Salvaging items arnt giving any more AP?
I have repeated 198 times, and still get pop up for achievement reached after salvaging 200 items. But it doesnt increase after a certain amount. It went up by 1 ap after repeating this achievment about 10 times, after that nothing again. So it comes and go. But for the most part it’s not registering any achievement points. I thought this achievement is suppose to be infinite.

It only gives 250 achievement points max, so 125 repeats (2 AP per 200 salvages)
