Error Loading Scenario File: This map could not be loaded because it had too many obstructions. Try widening the corridors and reducing the number of small nooks and crannies to correct the problem.

How do I get around this error without messing with the terrain?

The tileset is the indoor one.

That tileset is called installation.

The problem you are having is a very, very rare one. The only way to fix it is to edit the terrain, as far as I know.

Is that my only option?

Is there a limited amount of space allocated for terrain the the .chk or something? I don't understand why this error occurs.

I think it's a rare and very unlikely combination of terrain and doodads in some place that does something bad to the corresponding section of the .chk. If I'm not mistaken, editing the terrain in the problem point will overwrite the .chk section, thus fixing it. The hard part is finding the problem point.

If it's a single point that's causing this I will try to locate it and get back to you guys.

Jesus. I have to solve less integrals. I didn't mean the problem is one tile, although that might be the case.

Best method is to remove half of the terrain. Check. Then you'll know in wich half the problem is. Then repeat the process for that half. This way you should be able to find it the quickest. Note, that this problem is so rare that I've seen only 4 cases of it in all my time as a mapper. And only in one of those cases it got fixed. So don't be surprised if the method I suggested doesen't help. If that is the case, you can always try to get back to an earlier version of the map.

Okay, so I decimated the 'trouble spot'. Tried to pinpoint an exact location, but it may just be that blizz doesn't like excessive 'nooks and crannies', which sucks because that's how I'm making the terrain busier

i got this problem because i placed too many of the same custom doodad on jungle.
