As T3P3Tony said there could be a tool change in the actual gcode. 
Another problem could be that your customer set the temperatur for the first layer right but changed the temperatur of the other layers. I know this from the prusa slicer:

Hi there,
In fact you could run the mesh compensation with G29 S0 just once. After that the heightmap is saved. In your start gcode just then just need the command G29 S1 to load the saved heightmap. That's it, works perfect for me!
After some prints if you see that the compensation isn't perfect anymore you just run the mesh compensation again with G29 S0 and your good again.
