After some encounters i've narrowed down the bug in a test environment. When making a craft, logistics bridge automatically breaks down all recipes to their base components. I created a relatively simple albeit maybe over-the-top test setup that crafts a Signalum Upgrade Kit from Thermal Foundation that ends up with more than 9 things in list of ingredients
. At some point in AE2's process it tries to put these ingredients in a vanilla crafting grid in some way, which leads to an
ArrayIndexOutOfBoundsException.

I've found that this can be fixed by setting the bridge to "Simple Mode", however looking at some of the other issues it seems that switching to simple mode is a fix to some other problems. What is it that makes "Smart Mode" "smart" then? And why is it the default option in its current state?

I've now realized that Simple Mode results in a lot of "Can't keep up" messages that cause apparent server lag despite the ticks per second being 20, i suspect it has something to do with #49 in some way

Please right click the AE Bridge with a stick to create a profiler report, and please post it here.
