I think I found a bug...
This is my setup:
MFFS Force Power Gen. V2 (Equipped with an MFFS Generator Injector and an MFFS Card )
MFFS Projector V2 (Equipped with an MFFS Projector Module , an MFFS Card , 30 x MFFS Projector Field Modulator and a MFFS Projector Upgrade )
MFFS SecStation. V2 (Equipped with an MFFS Security Station )
A chest next to the SecStation containing my ID-card
At first, this setup works perfectly. It generates a large force field around my base on my server. After a while though, I am unable to turn on the projector itself, rendering me unable to power up the force field. To make it work again, I have to restart the server.
If you need to see it for yourself, Thunderdark, you're welcome to join my server. Just let me know, and I'll PM you the server details :)</power>
I had this thing too (until last update). Try removing and placing again projector.
