(Does not happen when running without Mechanical)
crash-2016-03-07_16.10.13-client.txt

Got exact same problem, Without this, it runs smoothly.
Mechanical is a rather important part of P-Red, IMO. Tho' WE got loads more mods on our game.

I think there is an accidental dependency on Integration. Install that for now, I'll fix it for the next version.

I got integration installed too, still get an Error, Not sure why. I even tried pre11.95 but that caused MORE errors (which i kinda knew, but hoped would still work :P )

The update fixed the issue. Thanks!
