Weapons getting deleted AGAIN!

Hello.
During play yesterday evening, I downed a Spetznatz Firebird and collected the loot. On opening the Plundra storage, my PVG90 4 crown has disappeared! This has happened previously only ALL MY WEAPONS disappeared when using storage. What was left behind were the sights and extended magazine. I noticed during the battle, in switching frim one weapon to the PVG90, the attachments had been removed and I had to re-attach them. I also noticed that the Avalanche account wasn’t signed into and the status was stuck on ‘Connecting’
I have recently received the Skyfire update and last night a patch was applied. After Skyfire, using storage has been quite buggy when selecting items, that’s, items not being selected when using the pointer and having to revert to the keyboard to properly select an item.

My system is;
PC Windows 10, Ryzen 5600x, GTX1050TI GPU, 24Gb RAM.
