Got on this morning, first thing I went to spider to buy a few stacks of phaseglass for legendary shards. I then infused a 750 pulse rifle into my Halflan-D to make it 750; that cost on top the other materials needed, a total of 2 enhancement cores.
I then went into my consumables and opened 7 Soltice packages (one of which gave me an enhancement core, at that time I had 82), and then did a few of EAZ runs to try and finish my blue set of Soltice armor.
After returning to the tower I dismantled a legendary pice of armor from the postmaster that was below 750 and it gave me an enhancement core.
Went into my consumables to see how many I had and it showed 2.
All I did was use 2 cores, and got those 2 back.
I'm not the only one to have this issue, after Googleing it I saw posts as far back as February after an update.
I know Bungie can't replenish "deleted or lost items" but I would like them check for a possible bug with the cores.
Now before someone condescendingly suggests I deleted them, you can't delete them in mass. To delete 82 cores you have to delete them one at a time and that would take awhile.
Umm, no. Since cores don't give anything in return the entire stack would be deleted. If you spammed opening packages and your inventory shifted you may not have noticed that you accidentally deleted the entire stack of cores. They will not be replaced.
If you tried to move stuff using the app or dim there is a chance they could be in your vault.
