Today I managed to finish the Ostelok Mission Stage 5 (yay) However, on the last 15000 killpoints, my mission counting seemed to reset. After going to the quarry and asked around, Kikki told me that it might (or acutally was) a display bug. I went back to hunting and hoped for the best. In the end, it showed about 14500/80000 killpoints after the display reset, and I finished the mission, confirming that this actually was a display bug. Currently I don't know about any other cases with other missions.
Same display bug have Oratan mission: http://arkadiaforum.com/showthread.php?8750-Oratan-mission-bugged
