Sadly its not the dev's fault, however i can give you 3 tips that may help you out with your problem.

1. be sure that you don't have any custom addon models for survivors or special infected since this will cause most custom maps to crash because the map doesn't recognize the custom models.

2. download the map while l4d2 isn't running or the map will glitch out and mess up, plus be sure not to disable the custom map in the addon menu or it will cause the map to lose its textures or have random crashes making you have to redownload the map again ( not every custom map does this but it can sometimes happen )

3. verify the game cache to be sure your not missing any game files by going into your steam library and right clicking l4d2 then clicking properties, then head to local files and click verify integrity of game files.


Sorry its taken this long for someone to respond to your problem when you've probably moved onto another game, but hopefully this helps.
