#1195 killed some brush entities from TTT.
This would fix it.
This issue was reported here:
TTT: Fix for #1195
Why is it using the direct variable over TriggerOutput?
The TTT ents were written long before TriggerOutput's data argument existed (8fef618). They can/should be changed to just call self:TriggerOutput with the value that's currently being set in op.param.
I'll change it later.
