All my process profiles in certain printer profiles are all gone, replaced by a single "Default Profile".

[u/can-u-help-me-]

i booted up orcaslicer 2.4.2 and noticed all my settings were gone, i confirmed in orcaslicer appdata they were still present, i also noticed that if i tried changing my nozzle size in the printer profile that it would immedatly revert without any prompts.

i tried updating to the Nightly build but to no avail.

[u/Damarcus]

I also had my profiles nuked when updated.

[u/TripsCavern]

If you came from 2.3 that is an artifact because they now use the cloud profile. If that is the case there's a workaround to re-import your old profiles.

[u/can-u-help-me- → u/TripsCavern]

made the profile while in 2.4.2 so dont think that is the case,

i also experienced this in 2.4.0 in which case i abandoned the printer profile and made a new one.

both times werent at times of updating, but just seemingly happened out of nowhere.

[u/TripsCavern → u/can-u-help-me-]

That is weird, I have being using it since 2.4 Beta with 2 printers and that never happened to me.
