Error : H-ARQ TX: fb is not for the pdu in this unit, maybe the addressed one was dropped

I am trying to implement a 5g communication network with 38 base stations and a variable number of user equipment which are UAVs. I need to run the simulation for a duration of a day. The system works fine until around 20,000 seconds and then end up in the error below.

<!> H-ARQ TX: fb is not for the pdu in this unit, maybe the addressed one was dropped

This runtime error error is thrown by src/stack/mac/buffer/harq/LteHarqBufferTx.cc when the fbpduId is not equal to the unitpduId. In this case is it okay to ignore this packet and drop it from there without leading it to the runtime error resulting in the simulation crashing?
