Fixed bug where joining to singleplayer world was impossible #219
Fixed bug where editable files would get downloaded anyway #233
Fixed bug which led to redownloading all the files on update
Fixed crashes when (dupe) mod got updated while it is in default mods directory
New behavior of duplicated files from default mods folder and automodpack modpack mods folder should work like this:
it moves what it can move
if the client mod is a duplicate of what modpack contains then it removes it from client so that you dont need to restart game just when you launched it and modpack get updated - basically having these mods separately allows for seamless updates
if you have client mods which require specific mod which is also a duplicate of what modpack contains it should stay
if it works in different way please report its a bug
Fixed bug where if you had 2 or more exactly same files they might have failed to download
Fixed bug where if in modpack was only one file, modpack was not available to download #230
