Change all calls of spawn to coroutine.wrap

[Ewanophobia]

Spawn takes ages to function depending on different circumstances, I suggest this get changed as it'll allow for a faster Nevermore.

This request is a bit too broad. There are reasonable use cases for spawn which are not covered by coroutine.wrap. As you are probably aware, spawn delays the execution until the next cycle, which can be important for certain operations.

If there are any cases where coroutine.wrap can and should be used, be sure to mention them.
