In order for this to work, you'd have to automatically take damage and drop to 0 or below so it can't be exploited and you return to bleeding out. The reason you come back dead is because this is a custom system, not regular vanilla nwn, and in vanilla you are dead once you're at 0 or below without exception. So if you log, it triggers the end of the custom scripts and bam, you're dead. It doesn't seem very feasible to fix this without causing a clunk of scripts that all could go wrong. Another way it could be exploited is if you log at -9 to give yourself a longer countdown. and even with only 1 hp, you can still flee, there's a delay in hostile actions of a few seconds. Enough time to get out of dodge.
