Hey everyone. Just tried a flight in the caravan and was struggling to maintain any speed with it at all. Also half way though the flight the AP stopped working properly and the VS decent values stopped working . The AP in generally seemed to glitch out. Anyone had any issues with this plane?

Two things you might try. First, be aware that if you're starting on the runway with engine running, the sim defaults to one setting of flaps down. I don't like it personally, but it's how the sim is set up. You'll have to remember to retract flaps after takeoff if you're not aware of this. 

The other issue is that the AP is buggy right now if you're using Active Pause at some point during the flight and then un-pause. To avoid that, set the control settings filter to "All" and map a keyboard or controller command to "Set Pause On" and another one to "Set Pause Off" which works without freaking out the AP. The AP also doesn't like time acceleration past a certain point.
