Dear Firefly users and developers,
I got problems with DLC generation. Here are my input files:

These are just simulations of simple reactions BMe3 + NH3 and BEt3 + NH3, that is 1D potential energy scans.

Firefly generates correct structures from symmetry-unique parts. The long B...N distances correctly defined with NONVDW. Nevertheless, Firefly reports "ERROR: UNABLE TO PROJECT DLC!". Any ideas why this happens?
