Do I just copy/paste my old saves from the old version into this one?
Sure, as long as they are from v0.16 upward there should be no problem!
Thank you so much!
Two things: 1.64 still has the load error.
And, I can't access half the discord channels
It works on all the saves I've tried it on, you should contact me on Discord, sending me your savefile and I'll also give you the needed role to read/write in our channels.
