Had a lot of issues getting FUBAR rc3 on the Vault.
Initially tried the regular uploader - two attempts failed at 90% done.
So, I tried to remote patch it in and that failed. It couldn’t process the link to the 7z file on OneDrive. This was probably more my issue than the Vaults.
Then I tried the FTP. Followed the instruction Rolo posted in the old Vault Forum archive and also posted at Uploading big files - Neverwinter Nights 2 - Neverwinter Vault. FileZilla would log in but the Vault would never show the directory, thus the connection would time out.
I finally got it to upload using the regular Vault uploader from the project page on the third try. So, is the Vault FTP broken?
