[3.5.0-rc.1] Premature execution of G54/G55

[tristanryerparke]

In some of my files I use G54 and G55 to move between two different working areas during the job (CNC). When using 3.5.0-rc.1 I noticed that I randomly get target position outside machine limits errors where previously these errors did not occur.
Upon inspection of the files I can see that the G1 commands that are sent are supposed to be in the G55 working space, so this error seems strange considering the commands are preceded by a G55 in the file. When copying this command into the console and running (after the job is cancelled by the error), I get the same machine limits error. If I send a G55 command, and then the "bad" line, it executes without any error.
My guess about the bug here is that there is a G54 command farther down in the file that is getting executed early, so I tried putting M400 and G4 S0.1 commands in front of these, but the issue persists.

Attached here are my config.g, override and a sample file which makes the error happen:
config.g.txt
config-override.g.txt
error_maker.nc.txt
The important thing to note in this sample file is that my machine has Y soft limits from -600 to 0, so a command like G0 Y20 will fail unless it is given in the G55 system.

I'm guessing this has something to do with motion planning and queueing, which I know there have been some changes to in 3.5.

Cheers,

@tristanryerparke What version were you using before when this worked ok? What board are you using?

@gloomyandy MB6HC with 4x 1HCL and 1x 1LC, was on 3.4.6 before.
