Mobile Bombyx Syaandana Replaces One of your Syandanas

Hi there, thank you for the report! A script fix that gifts an item wouldn't typically remove existing item(s), so this is odd to hear! Could it be that the missing syandana was a TennoGen item or a Platform specific item? 

Could you test that the item is truly missing on all platforms you have setup in your Cross Save account? If it is available on one (or more) but not all platforms, it is likely we're dealing with a Platform specific item. For example, the PlayStation exclusive Obsidian skin can only be used on PlayStation. 

Also be sure to check your full Syandana inventory, not just what is or isn't equipped on the Warframe(s) in question. Thanks!
