I've been having errors with a specific map that's almost entirely instance based, and I'd like to know the specific meaning of this particular message, since it's spitting it out 40 times. The map corrupted at one point because of a bad compile, but I managed to fix it with some clever use of notepad++.
Result from trying to run the game anyway - http://i.imgur.com/HL1VSKu.png .

Edit: It happens at the 'Generating object tree' stage of compiling.

Edit2: Some errors from the corrupted file ->
project.dmm:1:error: expected a constant
project.dmm:1:error: expected )

Edit3: Error is now popping up for every map I load that comes from the post-corruption map, including one from several months ago and another whose only relation are two instance-based grass and snow tiles. I'll try reverting my BYOND to an older version and seeing if that changes anything in the morning.

Edit: Reverting didn't change anything, but replacing the snow tile using find/replace with a different tile yielded some interesting results that are more palatable. I'll see if I can finish fixing the map in the morning.

Edit: Totally fixed. I had to go through the instances corrupted in the broken file and replace them with new instances in the working file.
