The error is: "The map could not be loaded because it had too many obstructions. Try widening corridors and reducing the number of nooks and crannies to correct the problem".
So, I have read the previous Nooks and Crannies threads, and I have tried their solutions to no avail. This includes copying all the terrain to a new map, removing all doodads, etc.
Now, this has happened to me with a Jungle 256x256 map and a Badlands 256x256 map, and I have not used extensively complex terrain. Far less complex and with less tight corridors than that Crescent Dyne terrain anyways. I do use a lot of isometrical terrain, and a smaller amount of square terrain for inside buildings.
I cannot stress how incredibly frustrating this is, as I have already completed the majority of my triggers, and I haven't even finished the terrain. There is still around 1/6 left to go for terrain.
How does Blizzard expect us to use 256 by 256 size maps to their full potential if they are going to censor how much terrain we can actually use?
Anybody with any suggestions at all to fix this pain in the ass of a problem would be very helpful.
None.
