Bugs observed on my Helix Floor 2.9.0 Firmware
1. Loss of sound while playing - connection to Powercab 112 Plus via L6 Link. 1 block used Amp Model Essex 30, Added Deranged Master, played a few notes and sound tailed off and crackled then silent.
2. Lock up of unit - think this occurred after changing preset, playing a few notes and then accessing Tuner
(Did the boot speed optimisation delay the loading of some modules to post boot e.g. Tuner?)
