Hi, I've recently ran into a couple of problems when running CraftingTweaks on the server side.

1. in pair with the Crafting Station mod I'm getting a crash when I guess CT is trying to access/create client side config (log is below)
2. there's a weird behavior with shift clicking items, as soon as I removed CT from server side, the issue was gone. Basically if you split a stack of items in a container and you shift click them back into your inventory, you'll see that the items are not grouped into one stack but instead they cause a visual glitch until you reopen your inv. (note: mouse tweaks is causing a similar bug)

Can't reproduce the second part with only Crafting Tweaks installed.

Thank you for the quick update, the second part was caused by secretrooms mod, but it was fixed by the author just now.
