Maps (multiple maps) from the market place, have a bug where custom trades built by the creators have a problem where ANY trades where you get a spawn egg are bugged, and when you make the trade yiu instead get a buggy egg which cannot be placed or used in any way. This seems to follow with my account no matter which device (tested on multiple devices) where the map still has the same problems. This bug also seems to follow with any commands concerning spawn eggs, like inserting eggs in a chest. This also seems to be a problem only with the my Microsoft account.
