Where did you get the "amoeba.prm" file from? It doesn't look anything
like amoebapro.prm, and clearly has illegal torsions in it.

The current (developers?) version has a little better error message:
Error: while creating dihedral 27-26-28-24 central bond does not exist.
But even the message you got is pretty clear: sleap is reading a torsion,
but finds a connection between atom type 26 and atom type 28, for which there
is no corresponding bond term.
In your file, the torsion list and the bond list are inconsistent; this
problem does not occur with amoebapro.prm.
