[quote]i had masterworked my class item and upgraded the other sets to around 8 or 9 energy. as well as infuse some of them with my pinnacle drops. i had got one to 1320, and the others to 1318, and pinnacle sources were dropping 1320, now that i upgraded to magnificent set it - - undid my upgrades and returned NOTHING (lost many cores and prisms and one shard) - reverted back to 1317 - pinnacle sources are now dropping at 1319 for me again, ever tho i had got a 1320 (yes they're +2 sources) i wouldn't have such a problem with this if it gave me back my resources or told me up from that it would do that. i would REEEEALY like a response from bungie , even if iots just "were looking into it" on this as their is no way im the only one experiencing this, and yall at least ned to be aware of whats happening.[/quote] This isn't a bug, masterworks are reset when upgrading, this has been the case since the first solstice post Armor 2.0, there are also multiple posts up warning those that are new about it.
