I realise there is little hope of ever seeing this again, but I was trying to take a medium ingredients bag out of my TR cache when it vanished before it appeared anywhere. I could not submit an in game ticket. This happened yesterday before the restart. The server was laggy so I thought it may have been that, but the bag never appeared.
If by any chance it could be found that would be wonderful...
I have my epic tokens in a large bag in my bank so at least I still have those, hopefully!
This was with Lyfa on Orien.
