Okay so I've been running into problems of map files exceeding the 4mb limit.
I've used MPQMaster, sometimes the compact flush works, sometimes I can't even select it which sucks because it greys out.
HeavyLock gave me most of the time these 99%, only once I got it to a normal percentage like 4%, but I lost some files from the listfile like for avatars, and some doodads, maybe when I was trying to get the listfile I did something wrong, not sure.
And finally Vexorian's optimizer, which didn't help at all, gave high percentages like HeavyLock.
Is there any good guide on how to optimize a map somewhere on this forum? Or on these tools I'm using?
2)Single Player Activation
Second problem is activating Single Player in RPG games and such. Read JJ's and Risen's Guide, I can't find what they tell me to find for in their guides with CTRL+F even.
And even when I try and think I got it, I try hosting the map but then when I select the map it gives me a error message and crashes WC3. Any help?

Sorry if this is a lot, I'm new to this whole thing, but I want to expand my knowledge and skills in this
