If the editor is crashing I'd highly recommend checking your unpublished\cookedPC\environments (and others) folder for any epic upk's that may have been accidently modified and duplicated. If you find any delete them.
Regarding your map preview pic, attach the emissive function, rather than diffuse, to your texture sample to give it some light!
If ya still can't cook it, let me know and I'll recook and upload it for ya!
The stock upk packages will often get duplicated by doing certain things in the editor. One example is if you go into the properties of a static mesh and look at the default material for it and sync the browser with that material. Doing this for some reason appears to try and make a modification to the package hence creating a duplicate of it, without you knowing.
i was testing the map and is very fun, the visuals are very cool, i just dont like dry grass, i was really foucused on the gameplay and i found some things:
-very much health packs (that makes very easy to steal the flag)
- some colision issues over some walls with static meshes
-and the doors woudl be work better with blocking volume ( for make walldodge there)
other thing but is more personal is... if you switch the armor 50 for the shield belt, the players will pay more attention on dominating the center of the map.
I don't have the original one so I can't compare, but the sky doesn't look quite right in a few spots and I can't fly everywhere to check out the map. You have created a good dark atmosphere and the tex/meshes look good. It looks like a good and tight CTF map. Um, I stopped playing the match a couple minutes into it; there seems to be too many windows blocking your path to go on multiple paths, especially the ones that really shouldn't be windows. This would explain why I couldn't fly everywhere. Sorry, but I don't really like this aspect of the map.
