Jesus christ, is the OP’s simple point really so hard to understand or is it common to simply not read messages before posting here? He clearly statet what’s the problem, he made examples, he even linked the wikipedia article. It’s that simple:
If the first condition is false already, Blueprint shouldn’t even evaluate the other pins connected to an AND node. That’s not only more elegant for null-checks etc., it’s way faster, too (for obvious reasons.)
And yes, it would be great if BP would behave this way.
