XY-Wing 34-39-49 pivoted in r4c5; r8c8<>4 solves it.
Also Type 1 UR 23 in r13c14; r1c1<>23.

A BUG+1 pattern occurs when all cells are bivalue with one trivalue. Or BUG+N is all bivalues with N trivalues. BUG+1 and 2 are commonly played, with +3 played less often.

That cell with an extra candidate may have any number of extra candidates. IOW it is polyvalued.

I'm sure your definition is correct. So a quadrivalue cell is a BUG+1 pattern, but two numbers have to be accounted for, so to me it's a de facto BUG+2.

I made that same mistake when learning about BUGs, but in the BUG+n expression, the 'n' is the number of cells with extra candidates, not the number of extra candidates.

Keith, I didn't know there were any sides to take. I'm with Ron too. Maybe I didn't make it clear, but I was trying to concede he was correct when I said "I'm sure your definition is correct."
