mb-reledit-set_instruments does nothing

[highstrung]

After selecting instruments to change and clicking apply, nothing happens.
I think this is a simple fix to change on line 32 to use attr.typeID instead of attr.type.id :

|| rel.attributes.map(attr => attr.typeID).includes(fromAttrId)

Making that change locally seems to work for me at least (Tampermonkey 4.19, Chrome, Windows 11).

Actually that's not correct. The change above makes it add the new instrument, but as a new rel rather than editing the existing rel. Looks like there are similar changes needed elsewhere in the script.
