Here is my current config: http://pastie.org/8032258

What I've been trying to do is get the potion effects to all work even if the fields are overlapped. For example, if I have 3 fields near each other,one giving night-vision, another giving speed, and the last giving jump, the spots where all 3 fields overlapping should provide all 3 benefits.

However as it stands the first one place overrides all the others allowing for its effects to be present and none of the others. Is there a way to fix or enable the overlapping that I'm missing?

==EDIT==
After a little more messing around with it it seems its not the first you one place but rather the first ones whose field you enter and it remains the only active one until you leave.
