I updated this puzzle to disambiguate there being multiple solutions already, maybe you were solving the old version? There is a logical path through the whole thing, although some of the early steps are a bit involved. It seems hard to me but some solvers have given it a 3. It doesn't have enough solves yet to have community difficulty rating here.

This question is indeed the only solution

I've gone through the whole solve process multiple times and can't see how there are other solutions. Specifics of how the other solutions vary would be very much appreciated.

The puzzle has multiple solutions. You might want to add another thermo.
