So I moved some things around in the tank earlier today and the digital thermometer has gone back down to 92-93.

I have herpstat, and I think the probe is rather large, I also had one of those thick zoomed UTH pads. The problem I ran into was that the probe made big air bubble in the middle between the pad and the glass, so I would get a temp reading from the probe that wasnt actually reaching the glass, also The zoomed pad produced the most heat at the base (by the plug) and the least on the other end. What it meant for me, I would get 5 different temps from 5 different spots.

What I suspect is that the area where your herpstat probe is in a spot with a lower temp than other parts of the tank, which means that if the probe is at a spot that is only 92, the some other parts of the pad could be a nice bit more than that. fix would be to just lower the target temp on the thermostat down until you dont have any spots reaching higher than 92.. problem was for me, this left me with a 6x6 inch spot that was my "hot spot".. I ended up replacing them with reptile basics heat pads and all of this was solved.
I have a zoomed. Up until the last couple days, it's been perfectly fine. I guess the herpstat probe just got moved off the glass or something.

You should move the thermostat probe between the uth and glass and put it wherever the hide is over. How do you have the probe fastened down? It is very possible your snake has moved it a little or the thermostat probe is not down against the glass, this is the reason why it should be sandwiched between the uth and glass. Move it and then you may need to up your thermostat a little do to the loss of heat through the glass. Your digital thermometer is fine where it's at.

Yeah the thermostat probe is in the tank. The only way the probe is being held down is the wire going under and in the hide with some substrate on top of it. Would there be a better way to make sure the probe doesn't get moved if it's inside the tank?

If putting the thermostat probe between the glass and UTH, can you take the UTH off the glass without ruining it or something?
