I have a batch of venison snack sticks smoking right now. The INT temp hit 129 and then stalled out for over an hour. The INT slowly got up to 136 and then started going down? Smoker temp has stayed the same and I am using my Maverick to monitor. Has anyone ever experienced this before. INT dropped back to 130 and after another hour it is back at 136. Sticks have been in the smoker for 6 hours now. Started low 140 and now yo to 190 smoker temp. Any advice?
