Objectives

Core Existence: Total (max +5000)
Ensures that at least 32% of residues are buried in the core of the entire solution.

Residue Count (max +2200)
Penalizes added residues at a cost of 55 pts per residue. Players may add up to 40 residues, for a total of 220.

Buried Unsats (max +500)
Penalizes polar atoms that cannot make hydrogen bonds, -150 points per atom (not including symmetric copies).

Interaction Energy (max +500)
Monitors that all large PHE, TYR, and TRP residues are scoring well.

SS Design (max +500)
Penalizes all CYS residues. Penalizes GLY, ALA residues in sheets. Penalizes GLY, SER, THR in helices.

Ideal Loops (max +500)
Penalizes any loop region that does not match one of the Building Blocks in the Blueprint tool. Use "Auto Structures" to see which regions of your protein count as loops.

stuck with one non-ideal loop...

Just like puzzle 1903b, this puzzle features a non-ideal loop than can't be fixed. It's between segments 90 and 91 at the start of the puzzle. The segment numbers can change if you add or delete segments.

As Boots pointed out last time, the two segments aren't even part of the same chain, and there's no way to change that. It's not clear why the ideal loops filter thinks they could be a single section of loop. It's one of those Foldit things, but everyone will lose the same 100 bonus points, so it's a level playing field.
