Hello Emathor, You are able to see how many fragments you have by selecting the dreadnaut in orbit and to the side of the map, it should say /50 Calcified fragments. The tracking website is very useful, but it has a small flaw. It tracks the fragments of all your characters at once. So it will say you have 45 but you might only have 44 ok that character because you picked up the missing fragment on a second character.
