Hi, I was playing today and I believe some skillpoints were somehow "lost" on my account before I could spend them. Here's what happened: I finished a Job and reached the next level, and got the standard "You have reached yadda yadda" popup in the upper-left corner. I decided to spend my Stamina before I went to allocate the skillpoints, so I did 3 quick Fights. During the second or third Fight (against another user, I don't recall which) I received a Fight achievement, I believe for consecutive wins. This achievement granted 2 skillpoints. I noticed then that my levelup notification was gone, and when I went to the skillpoints page to spend them I only had 2, not 7. I never spent the original 5, they simply disappeared.
