Fix to spamming interaction while gathering

Using an existing variable, shouldn't conflict. If it does it will just
mean you can't pick up items off the ground while gathering items in a
field... makes sense.

No "then" needed

So apparently this issue goes deeper than I was told. There is a way to
make your inventory infinite and when you gather a drug, you can then
take an infinite amount of drugs to the processer and process it all at
once.

I am hoping that this fixes it, and I have the name of the person who
currently uses it so we can monitor his data to see if it's still being
abused post-patch...

Really annoyed by these guys that are using this, because they have no
idea that what they are doing is wrong, and are going out of their way
to do it even more before it's patched out.
