Hello.
@Hekusen are you using Pause At Height with "By Height" or "By Layer Number"? There is a known glitch when using "By Height" and there are Z-hops in the file (or if you are using Adaptive Layers).
Cura reacts to the last Z it sees before the pause and if that was a Z-hop (or an odd adaptive layer height) then the resume height can be wrong by the Z-hop height.
Have you opened a gcode file to check what's going on with the Z around the pause? If you search for "M0" (or whatever pause command you are using) it should jump right there.
From the point of the pause - search for " Z" (space Z). Each Z value should be near the print height, and then finally it should drop to the print height and the extrusions will start again. That's the plan anyway.
You could post a gcode file that exhibited the problem as well. I have an Ender 3 Pro and PauseAtHeight is one of my most used plugins. I've never had a problem with the resume height. As a rule - the printer goes where it's told.

Sounds like a hardware issue where the Z movement is going too fast for the stepper to keep up? Do you know how to play with different Z speeds and determine what is the max speed (test both up and down) before the printer can't move fast enough? Once you know that speed tell the printer to use half that speed as maximum Z speed. Z speed isn't all that critical for printing quickly since the Z only moves a tiny amount between layers normally.
@GregValiant what do you think?
