Lobby error didn't let me roll for items.

Today i was raiding with my static and we cleared Titan for the first time as a group. We've been raiding together since 3 years already. While we were at 0.7%, the battle lagged and i got dced from the game. I could hear them in discord that the RDM weapon dropped (i am the rdm of the group and been playing it since it came out.) I tried to log back in quickly and I got lobby error several times, and i couldn't log back in time for the weapon; they even waited the whole timer for me to come back in.

When i came back, after like 10 minutes, i was already outside the instance, and locked on Titan for the week. I did send a ticket from the game and from SE support. I also post this here for any tips if i can do something else for recovering the loot, or at least not being locked for the week in Titan, since i didn't even had the chance to roll. Thanks in advance :(
