Is this strange/should I be concerned that something is not working properly?Concerning this specific question, in addition to general numerical problems, this might specifically be related to modelling mistakes leaving some free flows into the model. Free flows are one of the many causes of numerical problems. You should check that the QA_check.log produced in the working folder does not contain errors or warnings, or if it does, you as the modeller know that they are in fact harmless.
Specifically, warnings under the following title indicate likely free flows, and those with IO=OUT are most likely serious: *** RPC in TOP not found in any ACTFLO/FLO_SHAR/FLO_FUNC/FLO_SUM
