AU plugins not appeaing in Logic after installing mpc softwa

Does anyone else noticed a couple of au plugins disappeared within Logic after installing the MPC software and running an au scan to be able to use au plugins within the mpc software? MS20 & CS80v a.o. disappeared from my list and are no longer available within Logic.

YES. actually ever since running the AU plugin in Logic X, several of my audio/midi fx as well as other plugins will go missing temporarily (regardless of whether the MPC plugin is running).

I've found that the other plugins come back if you mess around in some other windows, switch focused track, stuff like that. annoying is the best way to describe it.

Exactly, the plugins started to vanish after I used the MPC as a plugin in Logic for the first time..
