Gunfighter Mk III Twist Axis suddenly stops working

Hello there.

Recently my Gunfighter Mk III has shown an strange behaviour in which sometimes the twist axis sensor will suddenly stop working and will keep sending a 0 value as if it was "pulling left" and won't respond to any other input. After this happens, the rest of the axes and buttons will keep working fine, but the twist axis will no longer be responsive and the only way to regain control is either unplugging the device, or calibrate it again.

I've already updated the firmware to the latest version, thinking it would solve the problem, but the described behavior persists so I don't know if it's a hardware problem with the sensor.

Below I include the info about my device and software, as well as some screenshots from the Joytester App, and the VKBDevCfg-C.

1 - Device model and version
Gunfighter Mk.III ‘Space Combat Edition’ SCG
2 - Controller Firmware version
v2.07.1
3 - Number and type of springs used
30A
4 - Тype of cams used
Avia-S
5 - VKB original software
VKBDevCfg v0.92.06
ZBootloader-C v1.90
6 - VKB Joy Tester

7 - VKBDevCfg screenshots

Is there anything else I could check, so I can fix the issue? would some sort of cleaning/maintenance process on the hardware could help?

Thanks in advance for any info/suggestions.

Did you pressed the Default button before calibration?

Yes, the Default button was pressed before the calibration, but the malfunction keeps showing up after a while.

Open up the grip and check the magnet, which is on top of the twist module. Also see if the board on top of the magnet sits properly in its rails.

I've realigned the magnet of the twist module as instructed and the problem hasn't shown up yet after a couple of days of testing the stick, so I think I'm marking this one as solved.

Thank you very much for your support.
