well thats not a 100% true statement.
if like A Cow does you run the server and client on the same machine, there is a remote possibility that razor running attached to a client that is on the server could possibly hang or cause some other process to hang. there by rendering a 98 machine helpless and force a reboot there by loosing server time (a time warp) and if this remotly possible system hang should happen to occur during a world save it could corrupt your current save file. Like i said this is an extreamly remote possiblility but i think phantom would have to agree that it is however within the realm of possibility.
aside from that phantom is correct there is no way for razor to crash the shard or zippy would not release it. trust to that.
