I agree with Cookie. It is a problem with the script, because the protocol just can't handle PSM changes at an interval like that, even if the PC is fast enough to handle it. Scripts shouldn't change PSM at a rapid rate like that, and users shouldn't be able to configure it like that either.
I'll be watching closer for this on newly submitted scripts. NiteMare, could you submit an update that doesn't accept too small values? I'd say 15 seconds as an absolute minimum, and like you said 5 minutes would make a nice default value. Will also contact the creator of swimming PSM to ask the same.
If anyone finds other scripts in the Scripts DB that change Name or PSM too rapid by default or that don't have the time interval setting limited, please post in this topic, or PM me. In general, you can PM me on the forum or email me at
to report broken scripts or scripts you believe shouldn't be in the DB.
