Harvest T4 boss, endless monster phase

This is a slightly different variation of the "not transitioning" bug.

(Yellow cat)
The plot had either 2 or 3 bosses, after clearing it I noticed the pulsing vines on the ground indicating monster spawning phase but the boss was either already dead(if there were 2) or invisible(if 3). The adds did not grant XP but it did brick the entire harvest for me.

I suggest adding a periodic fail safe to the code of the add phase and refactoring the conditions for the phase to begin in the first place(seems to only do so in open spaces, I would also change the circle attack to 'silence' instead of '**** you' but that's besides the point). Surely you have someone who could spare a few minutes on this infamous mess.
