As in title, Trade-O-Mat doesn't recognize items in Personal Safe or Vanilla Ender chest. It works with Vanilla chest.
I checked this on IC2ex-765, 821 and 822, with MC 1.7.10 and Forge 10.13.4.1448. It also occurs on Latest Forge(10.13.4.1614) and Latest IC2ex(822).
I also tried removing all mods without IC2ex, but result was same.
Is this a bug? And how do I make "SAFE" trade?
