Often when I join a server with custom maps, it automatically starts downloading maps, although I have them. I then get files like
trainyard.pk3.tmp , rhine2.7160a56d.pk3.tmp, etmapcycle.4f5f5bde.pk3 and many more. Sometimes my original files are emptied (0 KB), and I can’t join the server afterwards because of a checksum failure. I could turn of my autodownloads, but then I can’t download mapcycles

the problem is that there are numerous different versions of maps like for example rhine2 … you need to download those different versions
that leads to those mapnames with lots of numbers in them
imho its the fault of the mapper(s), they shouldn’t release different versions with identical names, only leads to confusion

Sometimes while downloading a map it stops downloading if the server changes map.
