Looks like mobs_mc is the cause here, but maybe the seaweed should have a nil check...

minetest.place_node is not among best parts of API ... it is really just wrapper around other stuff but built into engine and not deprecated so I guess it must be supported. https://github.com/minetest/minetest/blob/a463620edbe57071a7101297d33226507567ca73/src/script/lua_api/l_env.cpp#L459-L490

I would like to see place_node removed as it does not really add anything, however API function itself does not really have anything to do with nil placer.

This is bug in pl_seaweed (or in engine API development process) but not in mobs_mc which is just calling very simple documented API function.
