Fan Control reads but does not control fans when resuming from standby

Hi, recently fan control is not resuming from standby as expected. Fan speeds are read correctly it seems, but the curves are not applied.

How do you identify the curves not applying? How does it manifests?

Sorry, I meant that the fans are entirely no longer controllable when system wakes from standby. The fan speeds all move to about 60% speed (1200/2000 RPM) when awoken. None of the fans can be controlled manually either. A restart of Fan Control solves it immediately. The executable and json files are stored in a subdirectory within the 'Documents' folder.

This issue has arisen only a "couple" weeks ago. In total I have been using FC for about 10 months and never an issue! :)

So, I have been troubleshooting this further. I downloaded a fresh "install". Didn't help, same issue persists. Restarting app OR "refresh sensors detections" (ctrl R) always works to fix the problem.

All fans are connected to a Lian Li controller. The controller is synced to a the motherboard via PWM and speed sensor to the System Fan #3 header. The plugin is copied into the plugins directory.

What works - If I control all fans in Fan Control using only the System Fan 3 sensor and control, there is no issue with resuming from standby. But, controlling only one fan header does not offer much separate control.

Normally I would find the plugin faulty. However, in this case, a simple Ctrl R fixes the issue. So, somewhere, Fan Control is not refreshing all exposed sensors (exposed by plugin) when the system resumes from standby.
