Since proxy and server struct already have an internal last_change variable and we cannot merge it with the shared counter one, let's rename the last_change counter to be more specific and prevent the mixup between the two. last_change counter is renamed to last_state_change, and unlike the internal last_change, this one is a shared counter so it is expected to be updated by other processes in our back. However, when updating last_state_change counter, we use the value of the server/proxy last_change as reference value.
