G30 S-2 does not work in RRF3.2

[Marco Bona]

Hi, as the title says after updating the G30 S-2 command to RRF3.2 it seems to me that it does not update the position.
List what I tried to do:
-I made first print and had to raise the Z by 0.4 with babystepping
-I have corrected G31 Z value in config.g
-I started printing again but had to correct Z of 0.4 again with babystepping.

I believe that the G30 S-2 command at start of printing does not correct Z offset value.

I also point out some warnings that appear when config.g is loaded:

6/1/2021, 12:00:43	Warning: M307: Heater 3 appears to be over-powered. If left on at full power, its temperature is predicted to reach 365C
6/1/2021, 12:00:43	Warning: M307: Heater 1 appears to be over-powered. If left on at full power, its temperature is predicted to reach 686C
6/1/2021, 12:00:43	Warning: M307: Heater 0 appears to be over-powered. If left on at full power, its temperature is predicted to reach 198C

@dc42, I haven't tried to change the tool with this version yet, has the problem I exposed yesterday (https://forum.duet3d.com/topic/20721/tool-change-problem-think), been solved?
If you can help attach the report
