Two things:

1) Make sure the mani config option for not playing twice in the same round is disabled (It's towards the bottom, I cannot remember it). That should handle the slaying issue.

2) RPG has a tendency to screw with CSSDM in terms of starting HP. Usually RPGmod changes your default HP (at least from what I understand) when you level up. This happens as soon as you spawn. Then DM would change it back to your default health after spawn protection wears off. So my guess to the situation is as follows:
Spawn->RPG mod changes health->CSSDM changes health to spawn protection value->spawn protection time limit is passed and health is reduced back to standard 100hp.
So, in conclusion, you have three options: a) Disable spawn protection b) Live with no RPG mod health levels c) modify the CSSDM and/or RPG code to work together for spawn protection.
