MauranKilomNo. They don't get order to go to spawn pont. 100%
I have two unit chickens type. Wekense and strong.
Very Easy AI add one wekense chicken to random line every 450 frames.
It add string chicken every 980 frames.
Creeps spawn every 2000 frames.
So around 2 cockatrices add to each spawn.
Pyro very good vs chickens. 3-4 cockatrices vs 2 pyro = 0 cockatrices vs ~13 pyro.
