onPaint Experience Tracker issue

[Tillerson]

After many days and weeks of successful script, the experienceTrackers will randomly stop working and stay at zero. experienceTracker.getGainedXPPerHour(Skill.STRENGTH) will continue to return 0 for no reason, so it's not a problem with it displaying on the screen. All the other skill tracking functions stop working correctly as well. Persists even after restarting the client, and the jar is up to date. The actual value of the This has happened on mirror mode and injection. The only way it goes back to normal is to create an entirely new project and copy/paste the classes over, then it works fine. Anyone know why this keeps happening?
