Hi I am new to mapping and need your help figuring out the bugs on my new map, it's one of my first maps ever and I really need community help my friends don't like me and i thought why not have random people on the internet to accept my offer. I am open to any form of criticism and if you can provide screenshots with the errors that would be great! LINK: https://steamcommunity.com/sharedfiles/filedetails/?id=1506155508
