https://tf2maps.net/downloads/pl_midwest.8710/ According to the TF2maps forum thread, the cause of the crashes was traced to reaching the edict limit due to too many entities active. That issue was fixed a few updates ago, and after asking the mapper, they said that no crashes have been reported in later versions of the map. It sounds like it would be worth giving it another try.
okay I updated it and added it to the nominate list https://docs.google.com/spreadsheets/d/18ohmJhrUUs31JpniUqi28_zPpIAa_AJauwsEJNW5sLQ/edit?usp=sharing
