It only seems to take screenshots of kills sporadically, otherwise it spits up this:
stack traceback:
plugins/killshot/main.lua:51: in function 'make_file_name'
plugins/killshot/main.lua:58: in function 'dump'
plugins/killshot/main.lua:82: in function <plugins/killshot/main.lua:82>

What am I doing wrong?

Not sure but that's not whole trace.
Specifically it doesn't say *what* went wrong, only *where*.
If i had to guess, there's something in filename that shouldn't be there, but that's mostly a guess.

The errors.log just cut off after that. VO crashed when I clicked the little 'ok' button on the error window.. Seems to be working OK now, though.

Rather, there should be a line or two before that.

I suppose I should have saved said errors.log, but the plugin seems to be functioning perfectly now. Oh well..
