@NoVIcE(View Post) Saves with PIPE can't be uploaded. There may be a few other elements like CRAY. This restriction will go away when 93.0 comes out. It was mentioned in one of the changelogs about 1-2 months ago.
I made some changes to the save format, it's actually pretty surprising I can allow most saves to be uploaded.
@NoVIcE(View Post) Can you give an example command of what causes it? It doesn't happen for me. Also, what platform are you on?
@NoVIcE(View Post) @ChargedCreeper(View Post) This is a bug in the new randomizer (it is returning an unsigned int instead of a signed int like before). All of those issues you mentioned are separate problems. I'll have to take some time to fix it. I might redo the randomizer somewhat. I wanted something that you could easily call and say "I want a random number between X and Y" and other nice things, right now it's just a new rand()-like function.
