[DE] Continually being able to train past pop limit?

Not sure if anyone has noticed this. I'm playing an RM as Phoenicians right now, and am routinely able to train to about 56-57/50 pop. If a unit dies, units queued will still train up to this number instead of stopping at 50. I know in CD/classic data set this was exploitable and allowed you to go past your pop limit by as many units as you could queue up at 49/50, but I am playing the DE data set and my pop has not dropped that low. My army comp is chariots/CAs/elephants, so there's no Logistics shenanigans going on.
