Hi there, i found an error with AI AttackWave, some campaign units cannot be used as AttackWave, how can i fix this? For example if youll try to set Purifier Zealot ull encounter an error and lagbox(sphere) would appear. thx for answer.
Certain units like the Sentinel need an upgrade enabled via trigger to train. In your case it sounds like the AI is trying to calculate the tech path to a Sentinel, but as there is no buildable unit that can enable the upgrade, it's spitting out an error.
Try adding the necessary upgrade to the AI player via trigger.
