Plutonium

What would be the default location?

The game will crash and the bootstrapper stays open but it freezes. It only happens on servers that require mod downloads to play like Arcane Sniping or AlastorRoy just to name a couple.

Thanks for the response but unfortunately I've already tried that solution. The game will just download the mods for the server again and crash immediately after.

Same. Any server that has a custom map or mods causes my game to crash and the bootstrapper to freeze. I've tried every solution i could find and even uninstalled then reinstalled everything. I hope they find a fix soon.
