Happend several times, when doing a cleanup on an enemy base they sometimes do not spawn heavy tanks. An ally who did the first attack reported they did spawn tanks.
Merc camps do not spawn heavy tanks but flammpanzers and you have to research it in the library first, it doesn't just come free with the global age upgrade
You did not read my post. Go READ my post. The FIRST attacker noticed they spawned. Me, The SECOND attacker noticed they did not spawn. Dont troll me dude.
