But a G0 move along the X-axis causes no reactions on the Z-axis
Did you do a G29 A ? If so, please do a G29 W (What command) so we can see what the system thinks about things. Also, in the G29 W status report, it will tell you the 'Fade Height'. It defaults to 10mm. As the print gets taller and taller, the amount of correction needed (and applied) is less and less. Above the 'Fade Height' there is no correction. You can set the Fade Height higher if it makes it easier to see the correction. But really, the right thing to do (except for the fact you tilted the bed by 6.0mm!!!!!) is to move the nozzle closer to the bed.
You can also try saving the corrected Mesh with a G29 S 1 When you reset the system it should load automatically. It is possible the behavior is not quite the same without saving (and reloading) the Mesh.
