Lag spike while using TCA 3.6.2.2

[Tony422]

Happens in VAB. Especially noticable when adding new parts to large ships (Tried with SFB). Lag happens when: Adding part on existing ship. Changing number of mirrors. Picking up existing part on ship. Lag spike happen with mouse click, and will return to normal fps after about 1 second. The length of lag spike increase with number of mirrors.

I'm using a number of other mods for the ship so I can't provide craft file, but lag disappear when TCA is removed.

Game version 1.9.1
