what are you sure home pc?
im running on hamachi server which is a personal/home pc that run in a year. and we got no problem on map freeze
I run the server on first month, after that I decide to change host because i have a pc problem(which is my friends pc) . She run the server for almost 8months w/o getting map freeze, after that she feel like getting abused because her PC dont even rest ( pc only rest if there is electricity power loss or connection loss).
then i decide to switch the host to my another friend that was volunteered. he run the server for 2months w/o getting freeze too!. Then we decide to close the server because none playing it and hamachi change their settings
and btw we have players everyday above 50~100
