EN16 Fader Misbehaving

Hey,
My EN16 started misbehaving out of nowhere. One of the faders is all of a sudden super slow (not physically but in the cc messages it sends), doesn’t go to zero (stops at around 40), and is hovering around its position (so if I set it at the middle it hovers around there and it’s constantly sending updates, usually slowly inching upwards for a while after I don’t touch it).

It seems to be a software issue because I can get it working fine sometimes by disconnecting and reconnecting but it reverts to this behaviour in a while.

I haven’t changed anything, not wilfully at least. I did have the Grid Editor open before this started happening but I didn’t push any changes to the Grid.

Any ideas? I have a huge performance tonight and would love to get this fixed…
