What seems to be happening is that once the complexity of a sent message, in terms of a large number of (nested?) inline rolls, is too large, the API will randomly stop sending results as inline rolls in the result message if the sendChat callback is being used (this behaviour seems to be nondeterministic). This only occurs with --process, since GroupCheck sends a direct message otherwise. The reason that this is showing up now is that I recently made the formula more complex (=added nested inline rolls) to deal with the OGL sheet's nonsensical treatment of proficiency dice and general bugs in the API roll parser. I know how to fix this, but it may be a bit before I can test this properly.
