Hi, first let me tell you that my buddies and I really appreciate your mod have a lot of fun playing it.
I wanted to let you know that on several occasions, on hell hounds rounds, we had a dog stuck inside a window or even in mid air. That's not a big deal but it seems that they can despawn and not respawn elsewhere, preventing you from finishing the round. It happened to us twice recently on Ascension. We suspect that going too far away from a stuck dog is what causes the despawn.
If you can find the time to investigate that and release a patch or give us a workaround or command, we would be very thankful.
