For some reason I am creating a map which so far only contains units, terrain, and triggers. I've heard that sprites and doodads might cause crashes, but I still don't understand how my map can crash containing only these three objects. I have all the start locations too. Are there any trigging errors that can commonly occur?

buildings with 0 build time. Certain terrain causes crashes due to corruption. Many units will crash the game. Triggers dont really crash the game, but they can desync. Open the map up in staredit and save it, then try that one.

When does it crash? Does it crash instantly, or when you do something? What is that something?

Also, Check this: ______

The game crashes when I start the game.
I tried opening on StarEdit and it crashed too O.o. I'm guessing somethings wrong with units or terrain? Does StarEdit crash when you stack units?

Probably you placed SPRITES in SCMdraft or units which crashes (there is a "CRASH" list in sc-xtra editor where you can place 2 buildings which crashes).
Just to check: delete all sprites, then start map, tell me wheter it still crashes.

Are any buildings off the edge of the map?

There are no sprites in my game currently. I even selected the whole map for sprites and came up with nothing.
I moved all the units and buildings on edges a little inward already to be safe, but doesn't help.
What are crashable buildings?

Sprites should only cause a crash if you're using attack animations and other odd sprites, ones on doodads and doodads themselves should not cause a crash.

To find where the issue is, just go through your map systematically, delete everything in the sprite layer, test if it crashes, if not, undo, and delete everything in the unit layer, if that fixes the crash, look more closely into your units, get the idea?

If you're using buildings that are in StarEdit they shouldn't crash, others may crash, and most of them do, there's only like 3 stable buildings that aren't in StarEdit.
