I have the recipes in, as well as adding new spawner refuge shacks near each spawn point.

I still have the 7.7 world intact. I also have everyones 7.7 bases saved as prefabs. However, you won't find them in the 7.8 world. I had to start with a reset becase keeping the same world triggered bugs when you interacted with blocks who's ids had changed.

I can provide you with the prefab of your old base for your own use, give you a copy of the 7.7 world, on request, attempt to reimport your base into the 7.8 world.

Here are the bases that I explicitly saved aside as prefabs:

crxtower: crxt's tower, koleans's tower and villa, danny's base
peekasburg : the town that peeka founded and other players joined in on.
peekas pond: the structure and pond near peekasburg
sorrow's castle: the stone castle that lord of sorrow made
argville : arg's base and surrounding strucutres
crystals trollbridge: the burrow under the bridge that crystal and friends made
peekas lakeside resort: the cabins that peeka made

all other bases are still in that world, and I can provide you with the region files if you want them. you can get them up in 7.8, but they're buggy.
