Serious bug in Vaal Ruins (lost main weapon)

Dear All, good afternoon.
POE 2 issue here.

While running through new inst Vaal Ruins I used workbench to upgrade main weapon (druid talisman) quality from 20% to 21%. Then I was running through the map killing everyting (for a few minutes after using workbench).

Suddenly, I was kicked back to the main screen with an error message saying "connection to the server lost". When I immediately returned to the game, I found myself in the shelter. My weapon was no longer in my hand. It never returned after I restarted the game. I was not able to return to the ruins version of Vaal also.

So my weapon is gone now, so do my profit from this inst. Please kindly advise what should I do.

Thank you.
