I never noticed that on PEQ. P1999, yeah, but not PEQ, EZ, etc. That doesn't mean that they'll work, though - just that I've used them over the years on plenty of characters for testing, on various EMU servers, and had no issue. Most of them seem to not want to block MQ2 entirely, but they do use the anti-warp code, etc., that makes some active hacks not work.
