Thought i'd share some personal, hopefully interesting, WaW memory observations. I'm not saying that these are 100% fact, just what I've observed.
1. Random errors can happen if the game fails to allocate enough memory.
2. In extreme cases, World at War will skip developer errors that would otherwise prevent you from loading the map with developer and developer_script enabled. Errors encountered in-game(such as assertMsg) will still kick you out though like normal. Yes, the errors that normally would kick you out of the map otherwise are legit.
3. World at War has less trouble allocating memory in full screen than in Windowed mode.
4. For whatever reason, World at War seems to load assets from other directories without being told to(via mod load and devmap or map command). This can cause a wide variety of script related issues.
5. World at War seems to load(compile) a map a little differently each time(see 1 & 2) you do it.
