To anyone who is or will be doing a goblin and pirate invasion, do at night, spawn rates are normal when it hits nights, might be the same thing for the solar eclipse but because its during the day there is nothing we could do, and the same thing could be said for the blood moon but that's during the night and its fine as of the moment. Hope that helps with the invasions and a side note the frost legion isn't effected at all. Took me awhile to get a mushroom grass seeds, but I was able to find one. Also like most of the stuff i said earlier in this post( also which was said earlier in this thread), when hit, or hit by a choas orb acts like a kill point in the invasion. The reason I think this happens is when you destroy one or get hit by one it displays goblin gore and that triggers as a kill for the invasion.
