Quick question - what kind of a buffer do LXP Collectors have? I had a simple Enderman fall trap with a tier 5 shard and catalyzer, getting XP with the Collector. The Collector was feeding into a liquid tessaract and then into a Quantum Tank. Well, I turned off the farm a few days ago, when my tank had around 70 million XP, and still today I am getting XP - at this point I'm at 400 million.
Just hit 700 million.
