Thaumcraft 4 golems no longer drop XP

[pavelkomin]

I have a simple cow farm and I decided to kill them with golems. But mobs killed by golems no longer drop experience. Is it bug or it should be like that?

Do they have a visor?

Ohh, they need a visor to drop exp, it works now, thanks.

They've needed a visor since TC3.
