Under 0.572 of Forbidden Magic for 1.7.10, I noticed when I crafted a second set of Crystal Scribing Tools that I received about twice as many research points when both were in my inventory. Decided to launch a creative world and filled my inventory with them, and sure enough, I had 400 research points in about 3-4 minutes.

I'm guessing this is not intended functionality since it's ripe for abuse so I decided to hunt down the github and post.

I should probably mention that this functionality of the scribing tools is only available when Thaumcraft research is set to easy. Forgot to post that initially.

That's the intended functionality when research is set to easy. Guess I can look into putting some sort of limit on filling your inventory with them.

I figured that the tools weren't intended to stack the return based on the number of them in your inventory. If that is intended, than this is more of a balance concern than a bug and I realize how subjective balance can be.

If this is balance, maybe having a config option for the amount of research points returned or the number of ticks before the event handler fires would allow users to adjust to their preference.
