looks like the position returned from the entity/object was nil:

technic/technic/radiation.lua

Line 323 in ea14f60

local obj_pos = vector.add(object:get_pos(), calculate_object_center(object))

Do you know what objects might be around there?

Maybe it's because bed is a node that uses two blocks of space ? So that it detected a node on the bottom of the bed, but there was no node attached (but the head of the bed). So it caused the crash.

This issue has to do with entities, not nodes

a possible "fix" would be to add a nil-check to the returned position of the entity but the root-cause is not really fixed (nil returned from get_pos())

I think it is possible that disconnected/partial players can still be included here. If that's the case then what happens is exactly what happens here: instance is there and valid but everything returns nil as there's no data anymore.

Not necessarily cause but is a thing with certain stuff and isn't exactly a bug.
