I sure do appreciate everyone leaving me the BUG solutions!
An interesting BUG scenario exists in this puzzle because two peer cells share a possible true state for the same value.
Note: r4c7 can't be <1> because of the <15> UR. However, that would mean two steps to properly present the BUG+4.

BUG+4: r4c78=1, r6c2=8, r6c3=1, and/or r6c8=7
(7) r6c8 - (7)r6c4
(8) r6c2 - (8=7)r6c9 - (7)r6c4
(1)[r4c78,r6c3] - (1=7)r4c1 - r5c1 = r5c4 - (7)r6c4
Note: r4c7 can't be <1> because of the <15> UR. However, that would mean two steps to properly present the BUG+4.
