Corrosive Breath Not Corroding

For some reason corrosive breath just isn't working with my WE. I have disabled the tech requirements, and it doesn't say I need anything else. It changes the attack, but it just doesn't work.

I set up a melee situation and trained a chimera then researched breath, but it still did nothing. It enabled the second attack, but it doesn't do damage / time to buildings.

Umm, I think corrosive breath makes chimeras do bonus damage to buildings, not damage over time... I'm pretty sure their second attack is an attack that does more damage to buildings then their base... It doesn't actually corrode buildings, unless someone wants to argue.

What yiou need to do is make the second attack stronger and only target buildings. And make it siege. Or whatever.

Strange, because it has the field for damage over time and duration. Also it says it in the description, and has a buff for it.

Oh. Well then I have no idea.
