Hi Clement. Your first and last nodes seem to have incorrect digits. Should be (9=8)r5c9 ... (7)r5c1, right?

In 1s, a kraken 1-Fish r4\c5 + rfr4c3(#) => - 1r5c5; stte
1r4c3 - (1=78)r25c3 - r2c7 = r4c7 - (8=1)r4c5 - 1r5c5

Or add a starting node for a discontinuous AIC loop:
1r4c5 = 1r4c3 - (1=78)r25c3 - r2c7 = r4c7 - (8=1)r4c5 => - 1r5c5

Yes, I don't know what happened. It should go the way you have shown it. I am sorry.

That's not an AIC loop (they're always continuous and that's not). It's a Discontinuous Nice Loop (Type 2) masquerading as an AIC (not loop), and as such the best conclusion would be +1r4c5. However, with AICs it's unnecessary and unidiomatic to close such discontinuous "loops" (although not incorrect), so most would cut it from one or the other end:

either: 1r4c5 = 1r4c3 - (1=78)r25c3 - r2c7 = 8r4c7 => -8 r4c5; stte
or: (1=78)r25c3 - r2c7 = r4c7 - (8=1)r4c5 => -1 r4c3; stte

Myself, I might prefer the latter with a bit of additional compaction:

(1=78)r25c3 - r2c7 = (81)r4c75 => -1 r4c3; stte

No prob! I presumed they were just typos, as it was easy to see how you intended it.

That's not an AIC loop (they're always continuous and that's not). It's a Discontinuous Nice Loop (Type 2)

Thx SpAce for the catch...
Of course, I left out the "Dis" part, due to trying to post after happy hour! :D
