Very vaguely, what kinds of bugs? I'm curious. Can you whole-world clone the entire stack you're working on/with? 1. Verify the bug exists in your whole-world

Very vaguely, what kinds of bugs? I'm curious. Can you whole-world clone the entire stack you're working on/with? 1. Verify the bug exists in your whole-world clone 2. Chop bits out of one of the copies until the bug goes away, and/or see if you can copy the whole world to another machine (which you've probably already tried) Alternatively, perhaps let fixing this bug go, and as was suggested, use another machine (or a VM, if that's fast enough and it "fixes" it) for now. You might figure it out while you work on something else. This position is horrid to be in :P but letting go right now in this situation is sometimes the least long-term damaging solution.
