Bug/Issue Castle lord spontaneously dying from dialog error?

I have now on several occasions witnessed hostile castle lords (that is, the 'Glitch king' encountered at the top of fortresses and similar places) spontaneously die when spotting me.

According to my starbound.log, it's because it cannot find the right "being attacked" dialog:
[22:12:10.506] [Error] Exception while invoking lua function 'update'. (LuaException) Error code 2, [string "/npcs/bmain.lua"]:166: (LuaException) Error code 2, [string "/scripts/actions/dialog.lua"]:122: Dialog type dialog.attack not specified in castlelord
stack traceback:
[C]: in function '_ENV.error'
[string "/scripts/actions/dialog.lua"]:122: in function <[string "/scripts/actions/dialog.lua"]:104>

Unfortunately, none of this is of any help in actually fixing the issue. The only mod I have that makes use of that npc is Frackin Universe, and Sayter has made it clear it's not actually altering anything about it, just using it for some dungeons.

Any advice on how to correct this? It's not critical, but, y'know... errors are bad.
