OXT atoms wrongly placed

At least up to version 1.0.9, there seems to be an issue with adding OXT atoms to the terminal residues, with incorrect connectivity (bonds are too large to be biologically feasible).
This error, however, seems to be random. It does not occur in all systems, but it does occur even within similar ones.
An example of such a system can be seen below:

No source file, test, command, or reproducible input is named. Start by finding the code path that adds OXT atoms to terminal residues and reproduce the reported example, then verify that terminal OXT connectivity remains biologically feasible across similar systems.
