When I query a Point List for a Point (p in pl) it works OK unless the looked point is (0,0,0).
Am I missing something? Thanks…
Same result with the Code Block
That looks a lot like a bug. The built-in “Contains” command works however:
Thanks Dimitar.
Is it possible to call that built-in Contains from Python?
You can but it won’t do you much good because it gets borked up as well once implemented in Python … 
At that point I iterated through the list and it seems that the culprit is a point with coordinates 2,2,0 … weird.
I ran the list to 100k and it seems the only culprit is still 2,2,0. Dynamo crashes after 100k for me. This is an extremely peculiar bug 
Wow! Great Investigation Dimitar! Very strange indeed. First I’ve thought It was because of some floating point black magic
I’ve created a new issue about this.
