Hey there, something just happened in my files because when i'm trying to load my dungeon it give this error:
https://imgur.com/deuU1rL string "Arch.lua":0:undefined object: base_monster
I didnt even find any Arch.lua file.
Is there any people alive who knows this? I would appreciate much for your answer, because my working on dungeon is just halt. Thanks.

And it happens when I'm trying to load any dungeon..

I presume you have deleted the reference to the LoG file "assets\scripts\objects\base.lua". Or you have deleted the definition for "base_monster" within it.

Since all monsters of the original game (and usually all modded monsters) are referring to this definition, it must be present but ist in your case.

For the definition have a look at the file mentioned above.
For the definition of the path to the file have a look at "assets\scripts\standard_assets.lua"

Okey, I loaded my backup file so error are gone now. Thanks for answering.

But this is interesting..it happened 2 times. How files could be deleted even I touch the files?
