In this match, after Vikings destroyed 3 of my (Persian) castles, one kept spawning units (haystack didnt create). (I blocked itwith walls to keep the game fair, so I don't think it needs reset, as we won fairly after.)

The only explanation I can find is that the trigger that makes the haystack, after the castle gets destroyed, fires a single time, (when it should loop until done), and if the place is already blocked by an attacking unit, the haystack isnt places and spawn trigger still works.

Can you fix it, please?

Dude you should have counter yourself lucky lol, there is a simple way to make it so you can still have 4 spawns, if your ally has vills, not something I usually think about, and surprisingly few people know about.

put a wall on the spawn and it will never get blocked! yay now its not a secret..

This happened with me too, and I was very happy with extra ele

one could even do this with the enemy spawn and then have a nice little feed in cba/hero for example

good luck building on ice

oh yeah i didn't realise they'd changed it
