AI should break the loop after analyzing 100 sub-goals, which is just over 2 minutes in your case ;)

But yes, I've never seen such long processing times even on 252 maps.

I'm afraid that it'd crash after breaking the loop, as it happened in 0000985.

We need detection of loops in goal reasoning.

We have some loop detection algorithm since 0.95 and current AI worked normally for few months. Closing.
