Finished the event

On the last map pray to the RNG gods really hard to get the uppermost boss

Bosses:
Uppermost: 2 Finishers and a Crimson Winged Moth lvl42 - relatively easy
Right: 2 ???lvl Caterbros - a relatively healthy ~35k squad can take them down
Middle: ???lvl Ancient threat - Only boss that can give you trouble but two squads can take it down (or 1 squad at around 45-50k strenght)
