Fixes in the main branch and experiment: always on co-op

I fixed the DLC bug and waves bubbles not popping, in the process. Also, after talking and playing co-op with one of you, I decided to make a little experiment: always on co-op. You can access it in the BETA>public beta and if it works I'll push it to the co-op branch or maybe maybe the main branch.
