MY GF and I were playing, and she had put an item in the blacksmith, and when she retrieved it, it LOWERED in level. wasting emeralds, and making the item unusable. Why? Why do issues like this keep cropping up...

Edit 1: After further testing, the issue persists to shop items, items dropped in missions, and all blacksmith upgrades. Further bugginess occurs with the blacksmith, as the item level reported says it'll be between two specific levels, but gives back as the lowest possible level of what it should've been (for exmaple, it'll say level after upgrade is 23-23, but is given at level 188). This makes progressing in the game near impossible, as you can't upgrade your items, or get better gear without struggling to get decent enchantments for builds. Please dont' sit on this report, Mojang, fix it.

Edit 2: After further testing, this only occurs in online sessions for clients (not the host) and fixes itself once a client leaves and rejoins, but only after spending emeralds to restock the shop. It's most common after missions, as if the data for a player's power level is not resent post mission like it should be.
