Hello,
Where can I find 1.31 version installer (pre-clothing mods rebalance)?
In galaxy only legacy 1.63 seems to be available.
Kind regards.

If you want 1.31 installer at this point, and didn't download a local copy when it was available, your only option is finding yourself a .torrent.

Can't speak for any clothing mods after 1.31, but I do miss the 2 Million damage Nekomata. :/
